Bootstrap studio misbehaving

Hi, i want to know why and how to fix this: bootrapstudio (64bit) is not launching and the 32bit suddenly went blank after update on windows 10 64bit.

points to the "Contact Us" on the menu at the top of the website :P

Usually one would first try reinstalling the program. Then if that doesn't work try uninstalling and reinstalling the program. First find your ".bsdesign" files and back them up to a safe location, wouldn't want to lose those. Just in case you weren't already saving your projects to some place other then the default save location.
