Max.NET Unhandled Exception.

[bksong]

Could be coincidence but recently this week I'd get an error log on opening 3ds max 2014 (Win 7):

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.TypeInitializationException: The type initializer for 'Ephere.Utilities.Evaluator' threw an exception. ---> System.IO.IOException: The process cannot access the file 'C:\Users\Ben\AppData\Local\Temp\qs212nbz.dll' because it is being used by another process.

It could be coincidence but I installed and ran CCleaner before I started noticing this error.

Whenever I open any saved scene, I get another error box "Missing Dlls" that says 

FileName: Built-in Class:AnchorHelperObject SuperClass: 0x1160

I've read a lot of similar threads without many answers. I've tried repairing but I'm planning on reinstalling completely but hoping there might be an easier way.
