uhm... it should be impossible for him to switch to english/french/german server right now
can't you just change something in the url? like deleting "eu" and going with "com"?
try this:
http://en.gpotato.com/Transfer/Allods.aspx this should be the na site, and if it switches just edit the url to the one above.
it it doesn't work tell me
also it it does!
(edit: someone was faster than me
mod may delete this.. or not whatever...)
