Way too late now, but anyway:

The disk should be fixed by one lugnut. Grab the caliper and try to move it back 
and forth on the sliding pins. This should be possible with not too much 
resistance.
If the wheel design is sufficiently "open", this can be done with the wheel 
installed.
Of course, esp. as the wheels are off, taking out the lower sliding bolt does not 
take much longer (as Keith mentioned).
