Dimension Pro Standalone and REX files

Hi

If I run Dimension Pro from Sonar X1, it loads REX files just fine. However if I run Dimension Pro as a standalone app, it does not load any REX files. I tried to (what seemed obvious to me) copy the REX.dll and REX Shared Library.dll into the DimPro folder (C:\Program Files\Cakewalk\Vstplugins\Dimension Pro) where Dimension Pro x63.exe is located. This didn't make any difference.

Any ideas?

Thanks in advance
