a) you didn't enable all sets. Check Scanner->ScanResults->Setinformation if you got all sets enabled
b) similar, check if all systems are enabled. Scanner->Systems
c) maybe the zips are bad, check rebuilder's/scanner's warnings window for possible error messages
d) you run Vista and try to work with UAC protected folders
e) you try to rebuild to/from a folder where you don't have access to
f) check the rebuilder settings, there are some rebuilder advanced options like "skip creation when file exists in rompath" or "remove sourcefiles without rebuilding" which actually don't rebuild files
g) check the rebuilder log file (if enabled) or the rebuilder statistic window for info.
h) what do you actually expect? If you drop a file which already exist, it may be that quick.
