Windows 7 - Recuva 1.47.948

Good morning. I just updated my free version of Recuva to the latest 1.47.948 version using a Windows 7 64-bit machine and can no longer launch the program. It shows it running in Task Manager with a memory usage of 4,304k. Is anyone else experiencing this issue and/or is there something I can do to fix it? I have already tried uninstalling and reinstalling several times. I have tried with restarting the machine and not restarting the machine.

Any help is appreciated!!

Do you get the same if you uninstall (yet again!) and use the portable or slim version downloaded from here?
