So your first suggestion I could not follow through with because I am on a Mac and the file is for Windows
I was able to upgrade to 1.1.0 and tried downgrading to 1.0.9 but the file I got from http://web.canon.jp/imaging/eosd/firm-e/eosdigital7/download.html is not working. anytime I put the .fir file onto the SD card and try updating firmware it says that the update file cannot be found.
