Dude my buddy is using sandiboxie and his Cabal botting is fine as of..
OS - windows XP prof
Client - Cabal PH
Programs
-Sandbox
-Cabal Bot 1.04 for PH
-Cabal Rider 1.07(new) for PH
i don't know if this will work for EU client but at least try it for once
if you are going to play
*try deleting your GG file (Game Guard Folder and Game Guard.des) or just compile it a ZIP folder
*Open sundbox Cabal bot w/cabalrider first and try logging in first in sundbox
*if you have successfully log in and inside the game
*goto admin account and open cabalbot w/cabalrider and if you manage to log in to the game safely wait for 5-15 min to test it and if you didn't got disconnected at that time you can now play
Note:tell me if it doesn't work ill try to search for info's about you problem and ill put a link to the site

i haven't tested it yet in EU client so im not 100% sure about this but im 100% sure in cabal PH about this ^.^
tell me if it didn't work
