DL your rom again. Make sure it's the proper version for your device and rom version. Make sure you test it with Winzip or WinRar before flashing it.
You might also add formatting system to your wipes (data, cache, Dalvik). Most roms will also wipe it. Read the original post for your rom. Sometimes they want you to do weird things like mount system, format system, then install the rom.
Make sure you wait 10 minutes before you assume it's looping.
