Thank you for your reply, manny14.
After i resume the course i get an error like
"9/script.py has been moved. This will cause problems with this exercise, please move 9/script.py back to its original location, or reset your files"
and there are 2 options - Reset files and OK. If you choose OK nothing happens. If you choose Reset files you see a new message
" Reset your files?
This will overwrite your existing files, and reset your progress to the beginning of this exercise"
and you can confirm this operation or not. Guess that if you don’t confirm it nothing happens again. Even if you confirm this a workspace is restored but you are unable to continue with the exercise, because you can’t type in the editor.
From the change yesterday you are not able to even to skip this exercise and to continue with the next ones as they are locked now.
Really need some guidance from the support team or anyone else to figure out how i can continue with my course.
