ah alright. So I removed the launcher .exe, Cleared the cache, and changed my realmlist but it still would not connect to my other servers.
For whatever reason, I had to replace the realmlist with my backup before the changes would take effect, even after having done all of these steps. Perhaps it was just a odd glitch on my end. Thanks for outlining, I was worried I had missed something crucial and yet totally obviously (ha ha).
My system is win7 64 bit and is a Asus laptop. Not sure if that would make any difference with this (I do not see why it would but ah well) but perhaps if others ever have this same odd issue this may help to remember-always backup your original files, even if you are only editing text!
Again, thanks for the outline!
