AutoCAD Error: "base.dll" Can't find file.

Recently, I got a case in which the following errors came up when launching AutoCAD:

base.dll Can't find file.

Error loading dialog control file.

 

Semantic error(s) in DCL file.  See file acad.dce for details.

I absolutely dread an error message like.  Luckily, all I did was reset AutoCAD and everything worked again.  Please check out the post below for details:

Thanks to Aaron Morley for confirming that this solution worked!
