GPS USB OPENCPN....Help !!!

[1000 islands]

I purchased a GPS stick with the intention of installing it on a laptop so I would have a larger screen than my current 5" that I need to squint to make everything out........or glasses which I am constantly misplacing.

It is from a company called "officialnoaacharts"

My problem is:
I installed it and all seemed to be working fine then suddenly the screen went black, I could almost make out a chart but not very good.

I reinstalled it 3 times and still the same.

The odd thing is that when I right clicked on My Compter in the start menu, the drop down was completely black but if I scrolled down each choice was white.

This is way beyond my skill level, so maybe/hopefully I've just done something simple and it will be a simple fix.
