Ran into a small problem on CM9 A10 Pre3. Play Store was giving me the "error processing payment" when updating a free app. Looked at "My Apps", nothing there. Searched the forum for solutions, only thing I found was to wipe cache and Dalvik. Did that, rebooted, came up in fastboot mode with an error. Effectively the Android BSOD.
I did a full wipe using Leslieann's prep for new ROM zip. Doing it again to reflash the rom.
BTW, everything else was working really well. Looks great. just the one problem, probably me.
[edit]
OK, re-flashed the ROM and Play Store is working properly.
Still unable to use the updated version of Beat the Traffic. The older version (backed up) works fine. The update crashes constantly, but I don't think that is Quattrimus; more likely the app.
