Recuva crashes

Hello. Every time I try to run a deep scan for pictures I get a box that pops up and says Recuva has stopped working and windows will look for a solution.

It works when deep scan is not checked. Here is the message.

Faulting application name: Recuva64.exe, version: 1.39.0.509, time stamp: 0x4d09c856

I installed Recuva today so should be the latest version. I am running Windows 7 home premium 64bit.

Thanks
