[Major Error while loading mods]

the MAIN mod i am trying to use is [Rendflex : Entity map tool] and the problem also occurs with ALL other mods in the format of

.iwd/scripts/.gsc

... the problem is that everytime i load the mod and press "start" in private match i takes 4-7 minutes to go to loading screen, then when i get to the "loading screen" .... i get the message

Awaiting Challenge....1-25

also the progressbar does not

start loading until awaiting challenge number reaches {17}......... when the number reaches 25, the game crashes and and creates a dump....

Please Note : the game works perfectly without any mods...
