Error Code

I seem to be having a problem with Opus, If I try and open Control Panel or Recycle Bin I get the following error code and Opus closes and neither program will open I have not checked if any other program will not open yet.
ERROR CODE (0x0000005) occourred in thread 0x1108 at address 0x000000002321DE61

Any help welcome I have done a full virus scan and also run CCleaner all to no avail.

Please try reinstalling Opus over the top of itself to repair any DLLs and registry settings which may have gone wrong.

If that doesn't help, does the problem go away if you disable Explorer Replacement via Preferences / Launching Opus.
