lausianne on "File not synching - force possible?"

Hi,
sometimes files from GD are not downloaded. Currently there is a file on GD which I edited yesterday on one PC and I need it now on a second PC. I have a three days old version on that second PC. Usually this works alright. But now, after one normal and several forced syncs, I still have the old file locally and the new one on GD.
SyncDocs has an option to force uploads (which doesn't seem to work either, because I cannot upload the old file). But is there a way to force download a file?
Thanks!
