Have been running cm 10.1 on xoom since new nightlys came out. Did not have this problem until last night.Touched my Google Play Store app and I got a window stating " unfortunately Play Store has stopped". First tried deleting cache within app, did not help. Uninstalled and installed again. Seemed to work, but when trying to update a couple apps got the same message. Looked at permissions and everything looked good. Tried reboot and that did not help. Any ideas why this would be happening? Thanks.
