I CANT PLAY MULTIPLAYER PLEASE HELP

[StormFonix]

Okay, I cant play multiplayer because of error: "Failed to login".My login info is 100% (not 100 but 10000%) correct, but its again.
Then, after I patch kingdoms to 1.5 the entire game stop working.
The error is this: "Wrong disc inserted.
Please insert the original "Kingdoms" CD/DVD.
Please have a look at http://www.securom.com/message.asp?m=wrongdisc for further, more detailed information."
I want play multiplayer, and the kingdoms so much, I have bought the GOLD edition.

But the way, I installed a mod so I can play with aztecs,rebels,timurids and mongols, and another mod for Third age.Maybe it changes the entire game? What if I am maybe banned but I dont know, for installing these mods.
I reinstalled this game 4 times, (once deleted the entire SEGA folder) but it seems that the errors are again here.I tried doing every thing on this planet but nothing works.Please help

hi m8
Installing mod shouldnt block you out like that. It will only tell that your game is incompatible with everyone else when you log in.

Did you install the correct patch? There many different version of it, so makes sure you got the right one (Gold patch from correct region)
As for failed log in. Some time Gamespy have non working days, perhaps try again later? Game spy sometime wont accept certain character from nick, so try to change it to something standard first see if it works.

Well at first try re-installing the patch. It helps sometimes.
