If I restore your xp, you should also get those battle abilities maxed too, but if you wanna start over it is ok. If you change your mind, send me or any other leader pm on server.
Try to add resolution on the target line of your et shortcut (send to desktop a new one). Here is a sample of mine:
"C:\Program Files (x86)\ETLegacy\etl.exe" +connect "b2.clan-fa.com:27960" +set r_mode "-1" +set r_customheight "1080" +set r_customwidth "1920" +set r_fullscreen "1"
