I have been running RC release of SP1 for a few months with NO issues.

Yesterday I downloaded the SP1 release from link I found on this forum.

I am a little worried about uninstalling RC and re-installing SP1 because of the warning noted on this post

"using this file may violate the End User License Agreement from Microsoft"

I'm just wondering if anyone knows if there is any real differance between RC and the SP1 releases ?
