I had several problems with my controller on Win 7x64 as well. Best solution I found was gets a PS2 Dual-Shock and there is a cheap PS2/USB converter called Super Dual Box Pro that I had forever, worked great, plugged in, found drivers, connect, config and you're done. They don't make THAT model anymore, but there are 7 dollar converters, they're blue transparent plastic, you can grab one of them, they should have a driver as well, and less face it, PS2 controllers last forever and are EVERYWHERE. No need to buy a whole new USB controller at 25 bucks if the "Madcatz" craps out (which they all do...).
One thing worth mentioning is that you'll need to setup twice, once in windows 7 game pad settings, THEN open the FFXI config platform and assign and calibrate the buttons in the FFXI interface. As long as you do it in that order, you'll be fine, took me about a day to fight my way through the bad inter-webz answers...
I would stay away from Xbox and PS3 options on 64-bit though, major driver compatibility issues with the converters and assignment problems within windows from what I read...
Whitegate is pretty much always dead except for Salvage and NNI/NI. I know since I left (shortly after Aht Urg), Jeuno was revamped as the major hub due to Aby content, and now the tele points to the new expansion are also in Jeuno, and they are the new hot-spots. Make sure when you get on, hook up with Foo, we'll get you a pearl and you can start re-learning everything you thought you knew... lol. I'll be off for a bit, spending summer time with my son, but I'll catch ya in game when I can!
