SW2010 runs a few times then fails to load...

I am hoping someone can help. I load SW2010 SP0 with a home use license. Everything loads and runs fine for a day or so an then I can't open Solidworks. When I double click on the icon the hour glass shows for a few seconds and then disappears. It never makes it to the splash screen. My only fix has been to go into Control Panel, Add / Remove Programs and perform a Repair. This is painful as it takes about 30 minutes to complete. After the repair I can go in an out of Solidworks for a day or so and then it does it again. I also noticed it will fail if I reboot my computer. I am running 32bit OS. I have never had any of this type of trouble with 2009 but it runs with a SNL. Could it be something to do with the fact that I am using a Home-Use license? Just wondering if anyone has seen this type of problem or has any suggestions. Eventually I will get the 2010 SNL up and running,  but for now I am forced to use the home use license.SolidworksAdministration
