yeah so uhh some of the clients crash  like 2010L and 2011E and some others, i've already reinstalled novetus once,  and at first the issue was fixed but then eventually it started happening again. help appreciated

That never happened to me though. I'm not a programmer but maybe you should try 2011M instead. Does it crash or work perfectly?

Try installing latest stable version. Not beta one! I also had a lot of trouble in betas, like some maps not opening, or some clients crashing.
