Vista Ultimate 64-bit

Quick Summary: can't connect to internet but everything else works fine. most likely registry problem after using CCleaner. can't get into safe mode (gives only options to select device to boot up windows when F8 is hit). registry backup will not load in normal mode (states it cant import b/c keys are open by system or other process).

Everything was going fine when I decided to clean the registry with CCleaner version 1.39.502. I backed up the registry via the CCleaner backup utility. I cleaned the internet cache and the registry. It stated that there were 449 errors in the registry and that removing them would free up a total of 441 mb of space. I found that odd, but for whatever dumb reason, I continued on. CCleaner "fixed" all of the errors.
