One possible reason for this is that you have removed the password of XPMUser. If integration features are installed and enabled, you can not login to any Virtual PC virtual machine with an account which does not have password. Login to an account without password is only possible when integration is disabled.
If this is the case, do as told in this screenshot:
Then before enabling integration again, create a password for XPMUser.
