Jeff Beehler has just announced that the VPC distributed with VS 2008 Beta 2 will expire earlier than expected. Jeff wrote:
"We recently discovered that the VPCs we distributed as part of the VS2008 Beta2 release will expire on Thursday, November 1, 2007, much earlier than we had originally expected. Since the timeout is at the OS level, we cannot automatically extend the timeout period. As such we are currently in the process of reissuing the VPCs and expect to make them available early next week. " - Jeff Beehler
He gives a method to move any data you may have in the VPC TFS' to the updated VPCs.
