Another session running?-2009

Message says: "A journal file could not be created. Anothersession of Solidworks may already be running on this machine."

SW will still run after clicking past this message, but it doescome up every time I start SW.

2009, sp0 on a brand new computer;
Vista Business 64
Core 2 Duo ; E8600 @3.33 Ghz
8 gb ram
quadro FX 1700

update:

I just started this computer again. At Windows start up, I got thatannoying dialog box asking me if I had requested to start programSWIM. Is the Installation Manager trying to start up every time Istart Windows-even before I open SW itself? Is this issue relatedto SW thinking there is another session of SW running even thoughtthere isn't??

I am brand new to Vista, so I may be have configuration issues withsecurity settings. Any advice would be appreciated. Thanks.SolidworksAdministration
