I've been using the same magicjack for around 6 months now, 24/7. it has had some small glitches, but they have been worth it for the price
i tried over a few hours:
restarting the computer 4 times
turned off norton internet security
unplugged/plugged in the magicjack lots of times
tried launching it from \Application Data\mjusbsp\magicJackLoader.exe
I also let it cool down for a while-my room has been hitting around 95 this week, behind the 2 computers has got to be even hotter than that. found out the chips werent fried though when it worked on the other comps.
when i clicked "end process" i think i may have ended the mjsplash instead of the program, but should that have caused this problem?
I ended up fixing it by doing a system restore from a few days ago while in the middle of typing this up, and it works fine now, but I am really curious as to why it took a system restore to solve it. Of course that didnt fix the problem, it just made it like it never happened. did the end process delete one of the \app data\mjusb\
