So ive been rooted for a while now. Almost a year now. Ive been using all sorts of roms but recently(up to 2 months ago) i started getting errors. Games like fruit ninja and angry birds will not install on my phone. I have more than enough memory for them and they are downloaded fine, just fail on install. Ive tried all sorts of roms, wiping data/cache, and fix permissions. The market gives me this message "unknown error-18" any help would be great as this sucks.
