help uninstalling through adb

[dodgersrgood]

i uninstalled launcherpro from the most recent pe rom and then downloaded the most recent one from the market and now something like process.acore.(something else cant remember) is not responding. this has happened to me before and ive just had to reinstall the rom. there is nothing i can do because it keeps force closing every couple seconds before i can do anyting so im just thinking if i can uninstall it through adb i could get it back working again. how would i uninstall it through adb if it is located in /data?
