TestStand 2013 error 80004005

Question

For some reason whenever I try to run the Sequence Editor I get a "System Level Exception" followed by " Creating an instance of the COM component witch CLSID {B2794EF6-C0B6-11d)-939C-0020AF68E893} from the IClassFactory failed due to the following error: 80004005"
I have followed the published fixes including deleteing stationglobals.ini, running "Version Selector" etc to almost  no avail. The exception is that after a PC re-boot it will run but quite slowly; closing the Sequence Editor and re-starting it brings back error 80004005.
I have also tried un-installing and re-installing TestStand as well as complete re-installtion of DS 2014.
Short of re-formatting my hard-drive and starting again I'm not sure what else I can do.
Any suggestions would be most gratefully received.

1) Do you have any idea what might have changed around the time it used to work versus when it stopped working? Any new software installed? Some utility programs like graphics card utilities and virus scanners hook into all processes on a machine with Windows hooks and can sometimes cause unexpected problems. If you have anything like that installed recently, try disabling or uninstalling them and see if the problem goes away.
2) Do you have visual studio installed on your machine? What is likely happening is that an exception (really an access violation most likely) is being thrown inside the constructor of the engine when this problem occurs. If you can run seqedit.exe as the process to debug (with native debugging) with the Debug->Exceptions... dialog set to stop on thrown for "Native Run-Time Checks" and "Win32 Exceptions". And then when the exception occurs, break in the debugger, and do Debug->Save Dump As... to save a dump of the state of the process. Then attach the dump file here and we can take a look to see if it gives us any clues as to what might be the problem.
