Anything odd in the properties (size) of the account you are ACTUALLY in, even if the app thinks differently? I just solved the same problem, in my case disk space for profile one were all zeroes except for apps (3.45 megs)
Open a terminal window (I'm using CyanogenMod, you may have to download an app for that)
[Grant superuser privileges when prompted]
In my case the listing for profile 1 only had one item (app)
Now the potentially dangerous part, it solved my problem but do it at your own risk. Basically we're wiping the defective profile (which will backed up again when we switch out of it, so nothing is lost) and exchange profiles 1 and 2 to reverse the app's confusion.
rm -Rf *
mv 1 3
mv 2 1
mv 3 2
Now force close SwitchMe if running, open it, and you should be able to switch back to the other profile.
Wish you all the best! Let me know if it works for you
Thx man it worked!
No clue how this problem happened to start with though but I'm glad it is fixed now.
