Hello, and thanks for the forum, I wouldn't be getting anywhere if it weren't available.

I have pretty much the same problem. The first time I used Frostwire right after installation it worked fine and I downloaded a tune. But next time I tried to use it, it wouldn't start. There's no message, just the hourglass after double clicking for a second, then it goes away and nothing happens. Task manager doesn't show it open either. I've reinstalled it several times and tried turning the firewall off completely and starting it by right clicking and going through "run as" and de-selecting the "protect my computer...may make program run improperly" option. No work.
Also, when reinstalling it, some of the options that appeared on the first installation did not reappear; such as, whatever that was about de-selecting something through Windows, and the option of making your files available to others.

I don't know.
