If you have a router, turning it off and then on will reset the IP (if your ISP has that option enabled that is, some don't) if it isn't preset on the PC. You can also do this by going to the router's API, but I don't think you have the password for it.

Now, I checked a few proxy sites, but sadly, I can't find one that allows both key options: to submit data, and to get data. There is one that might work but it's not free.

Your best bet is to try the reset, or try some other PC sadly (in a different house/place mind you).
