Just to point some things out:
The number of times you have to try for the xtrap box to not appear is random. I've tried once and had it work, and the very next time had to try 10+ times. Just have to keep trying, it'll work eventually.
(in my experience, running the IM at the stage 10/99% mark doesn't seem to help)
In the same vein as above, if the IM box freezes at "Success!", the game comes up (black screen or loading screen), THEN the xtrap box comes up and closes the game, restart your computer and try again. I had this happen yesterday; nothing aside from a reboot helped it.
You don't have to equip training weapons/skill if you don't want to, it'll work without them. Probably increase risk of detection by GM if you don't equip them... *shrugs* I still equip basic junk, myself. I've never even SEEN a GM in-game, so :v
Don't enter the German server, equip a profile, restore, then leave (even after playing a game). Three of my accounts just got banned doing that, before I realized the problem...two for 2 days, one for four days. One of them had only been xtrap'd once or twice before, so it wasn't even up for banning yet. And what the hell happened to 2-4 hour bans for first-time offenders? Xtrap is such a useless, annoying POS...
This box can be clicked/Esc'd away, but you're still left with a black screen, completely screwed and unable to do anything. Trying to get rid of the box at login gets an a "Failed to authenticate" error after waiting a minute.
(no idea if other servers are affected. Europe server doesn't seem to be)
All the above observed on WinXP, SP3.
