Using Win7 Pro and the latest MS Internet browser.



Sonny Ray - quick question...

Did you download the previous build - 430? Without a problem? When?

If you did and did not have problems, it could be an issue with the latest updates to Windows - or the latest definitions files (for virus checking)
