There have been no problems on My PC's that run XP Home Edition, and the Lap Top is 5 Years old and only has 32MB Graphic Ram, 1GB Ram, Pentium 4 at 2.0GHz. Desk Top has 2 Pentium 4's Hyperthreaded, 1.5GB Ram, and 256MB Graphics RAM, both are DELL's.
Have you tried BCC Tech Support yet???
If not I suggest a call tomorrow between 10am and 2pm Eastern Time.
They might be able to help you, and if they can't call on Monday and ask for the Head of Tech Support. He is really good.
Hope this helps at least a little.
