That is what happens when I do the Ping thing.
I am experiencing a similar problem. I downloaded it in a different RO folder because I didn't wanna have to download the entire game all over again, but I do that all the time and its never been a problem before. I always copy a clean folder over with RO before I put a client into it (To avoid having like 90 clients in one folder). I get the "Failed to connect to server" thing after the character selection screen.
I tried downloading the patched client, and it didn't work, and all my RO is fully updated.
Any suggestions?
