KTK Hardpoints bug

Hey guys! I have a tiny bug that I have problem with. After the new kill streak system update everything was fine, all the kill streaks worked perfectly and with no issues. But few days back I decided to switch them and then the problem began. After I clicked on poison grenade every single kill streak on the list turned dark grey and now I am not able to choose any of them. Ive tried different ways to fix it but nothing seems to work. So now I am reaching out to you and hoping to get a solution for this problem/bug. I will be happy to provide you with any extra information needed!

Well I deleted cod4 and including the whole KTK mod folder with maps and all the other shit I can't reinstall it before 2nd of sept because I recently got a new house and my old house has new limited internet since I really dont stay much here anymore. But I will let you know if re-installing the game helped and re-downloading the mod to ofc. So slonder I hope your solution (the only one yet) will work.

I really need help guys None of the hardpoints are still working Tried reinstalling the whole mod and cod4 but it is still bugged

Depends what you are trying to ask. KTK was the only server I played when this happened.
