I followed everything in the guide, I even tried .py .exe .sh 32.exe. None working. If I'm the only one having this problem then I guess it's probably my tablet. Unlucky.
I had the same prblem with 14. Downloaded 15 and it runs, but it is having a lot of exception errors, I hit rollback, but when I go forward again I get the same exception. I still have not found an autosave that will work.
