What install program did you use for the update? There was some issues with V6Build2Setup1a.exe that might be at play. Based on the time of your post, you might have still gotten this version.
If you have run V6Build2Setup1b.exe, then I will give you some further information on how to correct the issue. If you have not run Setup1b, then please do so. If the program comes up asking to Modify or Repair, simply select Repair.
