I flashed an unofficial CM7 ROM and then Gapps, but when I try to access the Android Market, it crashes. It says "Sorry! The application Market (process com.android.vending) has stopped unexpectedly. Please try again." I've tried deleting the data and cache, removing and readding my Google account, and reflashing the ROMs but nothing works. Would anyone know how I could fix this? My phone is a 1st Gen ZTE Racer. I have previous experience with flashing ROMs successfully etc, so I know what I'm doing.
