I'm running Android 2.3.5 on a Droid Razr. MS has been working great until today. I try to run the program and it tries for a second then gives up. I tried rebooting the phone, reinstalling from the market. Nothing works. Do I need to reformat the phone? I thought I'd ask before going that far.
On your storage card you will see a directory called "MathStudio". Rename this to "MathStudio-OLD, disconnect your phone from your computer and then relaunch MathStudio. Does this solve the problem?
