Basecamp 4.4.7 - Will Not Launch

Downloaded Basecamp to use with my new Oregon 650T yesterday. It worked for a while and I closed it down. I went to use it again last night and it won't launch anymore. I get a split second of a progress bar appear on the screen, but it flashes up so quickly I can't even see what it says. I've uninstalled and reinstalled a couple of times but this has made no difference. Nothing has changed on my laptop, and the spec is as follows;



OS Windows 8.1

Any help appreciated to get it running.

Thanks,

Dex.
