Was using the previous rxp link, but noticed all wotlk content was suddenly gone after using the rxp gathering guide which is weird. I went back here to download the latest version, assuming that would fix it. When I installed it I noticed levels 1-30 didn't work, and most of wotlk leveling guide wasn't there. I tried uninstalling and reinstalling the file, extracted using the latest version of 7zip and made sure the previous rxp files were deleted before installing the new version. What usually causes this?
