| I've installed it twice and uninstalled it again both times, as it completely blocked all internet connections even though the firewall was turned off!
I had it running for about 3 weeks without problem, then it just decided to stop working. Luckily I had another PC on my home network to check if it was the PC or the net connection. Uninstalling SP2 brought it all back up.
You may have different results, but this is my own experience having installed it on the same machine twice, and got the same results. |
