After Effects CS6 Not Starting?

Hello,

I have hard drive issues, usually resulting in corruption or deletion of Windows dll's. Each time I run a chkdsk /f in my command prompt, it fixes the disk issues, but manages to delete a dll from one of my Adobe CS6 Production Premium Softwares. Last time, it was a dll from Premiere Pro. Now, it's from After Effects. It lost the boost_threads.dll file, which I replaced, but now the program will not start with error message 0xc000007b. Simply replacing the dll working in fixing Premiere Pro, but it won't do the same in AE...

Any ideas on what could be causing this and some fixes?

Thanks in advance,

Jack Reynolds
