Using SyncTou 2.1.100.0. I recently had to reinstall windows server 2003 on my laptop on the C:\ partition. I re-downloaded Synctoy and created the folder pairs. When I do a preview, I get "Exceptioin During Preview: Illegal Characters in Path". I then closed out of SyncToy 2.0 and have removed all the SyncToy_<alphanumeric characters>.dat files from the source and destination drives. I still get this error. Any logs that can be generated to see what it is actually complaining about? Any idea what this error is? I was not getting tis error prior to rebuilding the laptop.
