Everything is stock no overclocking or anything everything is installed as recommended. It is with all patches not just certain ones.
What version of Dimension Pro are you running?
Are you trying to insert the synth while the project is playing back?
Have you tried to insert 2 instances of Dimension Pro at the same time? Insert the first instance and do NOT select a program for it, and then insert another instance. Do this in a new project.
How are you attempting to insert the synth into the project.
You seem to indicate it is not patch specific.
As I said before, if I were in your shoes, I would remove everything related to Dimension Pro including registry entries, folders, and do a fresh re-install of version 1.5. Then rescan your VST's. That will probably solve the issue.
