If you receive this error:
"Microsoft Visual C++ Runtine Library"
"Runtime Error!"
"Program: C:\Program Files\Microsoft Office\Office12\EXCEL.EXE"
"R6025"
"- pure virtual function call"

Then you must do this:
Start Run : regedit (then click OK)
\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Exce l\Addins\RCMSOExt.Connect
There, i opened "LoadBehavior" and changed the Value Data from 3 to "1". I
click
on Ok, re-ran Excel and now its working fine.

If you need me to go into more detail on how i did this, let me know and i
can do the breakdown.
