Can you check your install files against the checksum values I posted, to confirm there is a problem with the download, and identify the corrupt file(s)? The DragonCommander-2.bin was corrupted the first time it was uploaded, but there could also have been a problem while downloading the files.
An easy way to do so would be to use the freeware (no install required) program
DVDsig, which I've included along with the checksum file for my download folder:
DVDSig-DivDragonComm.zip (9KB). Extract the zip file into your download folder, run the DVDSig program and click on Verify.
It is possible the updated file just didn't get to the server you re-downloaded from, so waiting and trying again may work.
