Exception deleting file: Stack overflow

I keep getting this error. Syncback thinks a file is in my destination location even though I've removed it. Whenever I perform a backup, Syncback crashes. When I relaunch Syncback the profile still says "running" and cannot be stopped. Please help. Thank you! Source and destination are regular SATA drives with no compression. The following error appears in my log file. I've rebooted, deleted the profile, and created a new profile and the error still occurs.

Not in source, Failed to delete destination: Exception deleting file: Stack overflow

Windows 7 SP1 x64
Syncback V3.2.26.0 (en_US)
