OK, this is directed more to the authors of CMBB than anyone else.
Is it really necessary to have a CD check in CMBB? In CMBO one, although it was annoying, it allowed a partial install of the game on the HD.
With CMBB, the game installs itself fully on the local hard drive and only checks the CD at the start, for no good reason. If the game is started without the CD in the drive, a message ,ala CMBO, appears stating you have to have done a full install (which has been done, as there is no other choice) but doesn't allow the game to run fully.
If this is an attempt at copy protection, it is pointless, as these types of protection have been bypassed before.
So, I hereby petition the authors to remove the CD check as part of the upcoming patch.
