Remote Desktop Manager has stoppe working

Hi,
I had RDM working on virtualbox windows 7 (64 bit). I had to redo my virtualbox since it was running on Redhat linux system and on estart had dll issues.
I did a fresh build of virtualbox windows 7 (64 bit) and installed my version of RDM 5.8.3.0. and got "Remote Desktop Manager has stopped working".
I uninstalled and installed RDM 5.9.0.0. and get the same error "Remote Desktop Manager has stopped working".
Any ssistance would be great. Thanks in advance.

Here is what I find in the windows application event log:
