first of all i had a problem with frost. after i pressed play on the site, the bar appeared (which was frost i believe) and nothing happened after that. i resolved this issue by downloading a ready-updated frost folder from another user and replacing mine. the game now launches properly. after that, i get a horribly low resolution and am directed to the server choice screen (with only core being there). the game works really slow, i cannot click any of the buttons. there are 3 possiblities i do here: 1. i press enter -> i am informed about disconnection and when i accept it, a long game guard error appears. i cannot read it though as the game closes the next second. 2. i try to click the buttons - nothing happens. they are really laggy, once i put my mouse cursor over them, they take like 2 seconds to lit up and do not react on clicks. 3. i do nothing and wait. after like 5-10s i get a gameguard-601 error, accepting which causes the game to close. i have spent 2h reading all the topics on this technical issues forum and none helped me. i have windowsxp, c++ redistributables up to date, framework 4.0 up to date, launcher is version .51, not .49. i have no firewall besides the windows-built-in one which however is disabled. i still added all the exceptions to it, even though it's disabled: every file from frost folder, l2.exe, l2.bin. i have no game-guard related files in the system folder which other solutions advise to delete. i also tried this: https://forum.4game.com/showthread.php?t=995 i cannot do the "disable dep" thing though, as i get an error that bcdedit.exe is not a valid command.
