"WD Sync has stopped working"

I use “WD sync” to synchronize a WD external hard drive. It has worked fine, but now whenever I want to open WD sync there is an error message saying: WD sync has stopped working and Windows is looking for a solution. Then it asks me to close the program before it even opens.

I also thought of reinstalling WD sync via the setup file i have. If I click that, there is an error message saying: corrupt file.

Can anyone tell me how to get WD sync up and working again? Thanks!
