Hi, needing some help with my desktop wallet (Windows 64 bit)

I can't get the wallet to open - due to "MinGW Runtime Assertion" box that pops up. It says "Assertion failed!..."

I also just realized that I probably need to update the wallet. (I've got 2.2.0.0). Would this be the reason for the Assertion failed?

I downloaded the latest version.

Now what? I haven't even opened the file because I'm not sure what I'm supposed to do.

I'd be grateful for some help from any of you experts out there. Thank you!
