My B4A is installed in:
C:\Program Files (x86)\Anywhere Software\Basic4android
and I started getting this message today after moving my project directory from C drive to D drive.
I didn't change the program directory. And all of the projects except one still work fine - I was just about to make a bug report about the Table class possibly not liking project directory on a different drive when I came upon this topic.
So, I will grab the newest beta version and install in a different folder and see if that fixes the problem.
...yes, it did fix it. But I have no idea why some projects continued to load and work fine and only 1 project threw the error.
