VBA Interface Error:Unable to run macro

Hello, 

Company wide we are having macro issues. We are all using:

Windows 7

MS V8I SS2 v8.11.7.443

Microsoft Office 2010

We operate on MDT CADSTDDs but have our own modified configuration file. Their macros have been created on a Windows XP OS and an unknown version of Microsoft Office. 

When we try to execute a macro, we are encountered with error messages such as: 

VBA interface error: unable to run macro - project, module, or macro not found

VBA interface error: could not find project or project file

In some instances we are encountered by errors such as this: 

Oddly, a co-worker's macros started working today as I post this. Has anyone else ran across this issue before? I have my suspicions that the root cause could be a compatibility issue with the macros created on an older platform and trying to run on a newer, updated VBA interface. 

Any help is appreciated, 

Vinny
