Oh man! You're all missing something :/ you can freeze the game and if you do it in the 5-second-pre-game-lobby-thingy... you know... you can hit the pause button
When you do it right the 5 second timer should stop and you can take your time changing the 0's to 25's, but don't take too much time since there's still this accursed gameguard... QQ
edit: When you click Advanced Options the window that pops up has a little button with two bars in the upper left corner. Click it to pause the game after the loading screen and before the actual games starts (in the 5 sec lobby).
Btw I found a video that pretty much sums it all up and I use the .erl remover. Sometimes it screws up your Gameguard permanently and you have to delete the Gameguard folder in your AVA directory to fix it.
Tip: Turn off the vid's sound ASAP!!

PS:
How much time did it take 'till you got banned? (and does the BG:Extreme->Easy glitch get you banned, too?)
