For 2 weeks I could not get into RV.net on this computer, laptop, or ipad.
A lot of phone calls to local IP for support and found somewhere down the line I was blocked by a server or RV.net for spamming if I remember correctly. Don't know how my name got on a list somewhere but gave up trying to find out.
The RV.net administrator was of no help and now I use a proxy server just for this site. (www.proxysite.com and its free)
It is my IP address that is blocked so anyone using my router will be blocked.
Try someone's laptop or whatever from your house using WIFI and see what happens.
Sounds like what you tried using was a translator, not a "proxy site".
Maybe the same?
