Ok, so i changed some settings on my Windows 7 64bit, and it said i needed to restart to activate the changes. When it came back on, i logged in, and got an error message saying: AtBroker.exe: Failed to run application properly (0xc00000ba). click OK to terminate the program. Then, i click ok. then continues to this blank screen of pure light blue nothingness. all i see is my mouse. it does the same thing on safe mode. Please help! its very frusterating.
