i've had the same problem :P
okay... i know what problems u have... i had the same just before and it took me 1½ hour to cinfigure out how to get it to work... well...
first of all shut down the MySQL and the Realms and Logonserver...
i'm totally sure that u have even put the AC repack folder into C:/Programes and files/AC
well.. that's WRONG!!! WRONG WRONG WRONG!!!
do this... delete the server (just for being sure)
then when u have to install it then it asks u where to install the package...
chose this: C:\
so it will install it directly on your harddrive...
remember to call the map for AC Web Ultimate Repack
så when u install it it should say this: C:\AC Web Ultimate Repack
now simply extract maps and run the server
everyone in here likes PIE!
