rogue

I've been collecting a lot of PlayStation 2 games lately mainly focusing on RPGs I never got to play, specifically targeting Mega Man Legends 2, Rogue Galaxy, and Steambot Chronicles. I loved MM Legends 1 and mml2 is more collectable so even if I hate it it'll be worth money, Rogue is cheap so...

when i'm in game in rogue spear lobby my mouse cursor freezes for a couple seconds as i move it and when the game starts online everyone warpes only i get it. firewall was off. compatibility options dont help. is it cuz of my vid card? directx? win xp? help would be greatly appreciated...
