I have BES Small Biz Edition, or so I think. It is running the latest SP, 220.127.116.11. I purchased a 5th CAL and went to add it and was told "The license being added is not compatible with the existing keys..." Basically I purchased a CAL for BES Full. I then found out I could upgrade to Professional for free and Professional would accept my CAL.
I d/l and tried to install SP4 to upgrade to Professional. When I run it I get "Cannot upgrade to older version." I tried looking in add/remove hoping that I could just un-install the SP's so I could get back to 4.1.3 and then step back up.
Any ideas on how I can get BES Pro up and running?
