Unable to obtain required memory

Whenrunning Cosmosxpress I am told to reduce my mesh size and when I doI get the error: SolidWorks is unable to obtain requiredmemory: Please attempt to free some memory and then pressRetry, or press Cancel to terminate your Solidworks session. If I free up memory and it is still not enough for Cosmos to run itwill exit my session of Solidworks. At this point I should beable to go back into Cosmos and change setting without it throwingme out of session. My VAR said it uses both physical andpaged memory. I added 20GB of paged memory and it did nothelp along with my 2GB of physical memory. I watch the TaskManager in Windows and it does not use much memory at all whenrunning. Is Cosmosxpress just a program that should not beused. I find it works for simple parts but if you havecomplex weldments it has problems with the solid mesh andmemory. Is this a Windows issue?
