The problem is that MOD Setup and Alternative MOD setup are the same and i can't install the mod... now the page that MOD Setup open is admin_mod_dbsetup.asp and Alternative MOD setup open admin_mod_dbsetup2.asp, how is it possible????
not really sure what you are saying. but i'll make a guess that you are trying to follow the instructions for a mod and it says to go into the mod setup to choose a specific dbs file. and when you try it, you are given the alternative mod setup that has a box to paste stuff into.
if this is the case, then all you need to do is open the dbs file in your text editor, copy all the text there and paste it into that box on the alternate mod setup page.
