Did you flash the appropriate ROM and GAPPs package? There are various types of GAPPs files and you need to make sure you have the correct one. If you have, then you may need to fix permissions. Most SU apps can do this for you, including Recovery. Consult with the ROM developer on solving the problem as well.
