I came across this problem during winter vacation. After some time I realized its because Adobe Flash Player is no longer in service as of 2021. So basically as far as I know the Cheongjae CD's will not work anymore. My way around it is to use the internet site T-Sherpa with a login I stole from a previous teacher, but it's not an ideal solutions as the CD seems to lag when run from a web page.
I'd really like to know if anyone out there knows if there will be a solution to this problem for the new semester in March. Will they ship new books with a new CD that can run with different flash program, I really hope they address this problem quickly.

I found the solution to this, I don't have much communication with co-teachers so been trying to figure this out alone. Go to the website T-Sherpa (you can search it in google). This is the website that Korean teachers use, you will need a password from a Korean teacher to login. Once logged click on 교과학습 then click on 영어(함순해) and finally click on 교사용CD 다운로드 (CD download). There is a new CD there, the style of the graphics has changed slightly. You may need to install extra plugins to make it work.

Hope this helps someone.

In the top right corner of the page below:

http://e.tsherpa.co.kr/curri/study.aspx?subject=A8-C1-40-EE-EE-06

It says 교사용CD 다운로드 (CD download).

You can download all the textbook files here, ask you co-teacher to use her/his login first as you need a login download.  The files are pretty big.  (Several GB)

We just downloaded a digital version of the books, which isn't as user-friendly as the DVD versions, but at least it's working.

You need a Korean teacher to create an account.

1. https://info.edunet.net/
2. Click on 디지털교과서 (Digital Textbook)
3. Have a Korean teacher sign up and log in.
4. Download and install the Digital Textbook Viewer (뷰어설치 및 활용).
5. Open the Digital Textbook Viewer program. Click either the + icon (only shown if no books have been added) or the download icon (upper right corner "스토어") to choose and download your textbooks.

This method appears to apply for multiple publishers. Because I'm using my co-teacher's login, I'm seeing all the textbooks my school currently uses.

I hope this helps!

Hey, everyone.

Trying to get ahead of this problem here and download these as soon as possible, but the downloads on T-Sherpa keep stopping after a few percent. Anyone else having this issue right now?

Okay, so I got the Cheonjae textbooks downloaded from Tsherpa but I have a new problem.

Some menus in the textbook don't work with the classroom touch screen. Anyone having this problem?

Specifically, If I start the program before turning on the classroom touchscreen, some menus work with a mouse at the computer but not on the touch screen, but if I start the program after turning on the classroom touch screen, those same menus only work on the touch screen but not with a mouse.

Anyone else? Let me know ;(

Okay, so now I see that this problem also affects the online version of the textbook, and, I tested it in another classroom in my school.

Can anyone confirm that they DO or DON'T have this problem? Either answer would help me solve the issue...

Again the problem is that you cannot use BOTH the touch screen AND the mouse to navigate many menus in the Cheonjae textbooks. You're only able to use one or the other depending on whether or not the classroom touch screen is on or off when you start the program.

Please help if you can. Thanks ;(
