OT: System Application Resources Exceeded?

Ok I tried to open a second session of SolidWorks and I got this message.
"SolidWorks cannot startup because the system desktop application resources
have been exceeded."
Task Manager says that I have 557MB Paged the limit says it is double that. Is it possible to up something so that I will not get this in the future.
SW2003 SP 4.1 and SW2004 SP 0.0 on windows XP.
Programs I have opened
MS Outlook MS Outlook Express Solidworks with VBA, API Help and Sldworks Help Fabriwin (CAD/CAM) AutoCAD Internet Explorer (3) windows Terminal Server (for access to our MRP system) and some anti-virus utility
It is alot but it shouldn't be too much. Not for XP or any semi current CPU
Because I know someone will ask. The reason I want to run a second session of SW is because I had opened SW2004 earlier to check something out and now when I opened Fabriwin to update a part that I had changed. It doesn't think that SW is opened.
Remedy without closing the whole SW session:
Start a new session open updated part and transfer to Fabriwin.
Thanks Corey
