That usually solves a lot of problems for people, to flash back to stock and then go to a custom rom. It's called doing a "flash dance".
If that doesn't work, you can also look into "task 29". It's really not as intimidating as people make it out to be, just download the splash screen version for the Herman (sorry I don't have a link handy). What you're describing sounds like a classic bad flash.
Btw, if anyone is using the Facebook tab and wants more battery life, disable the auto update. I'm getting much better battery life with the Aug 12 rom than I was with the July roms, but I just noticed it's updating 70+ contacts on my phone every two hours. That may explain why I get about a day on the battery
