Cleared out my old F@H software on my machines and updated to the latest version.

Some issues have cropped up:

My machines running a GPU and SMP: SMP runs 100% of the time but the GPU will fail to update after it submits a successful run. Both are Win 64.

My machines running only a GPU: Work 100% of the time. Both are Vista 64.

At a loss. Is it the OS or the combination of SMP and GPU? I did remove all roaming information etc.
Any help would be appreciated.
