Its just not working it worked at first but now it wont help?

Can you provide any more details? What isn't working? Is OBS not connecting to Twitch? Is OBS not starting? Is it crashing after you start it?

Its crashing right after i start a recording or something or a livestream i finally figured out how to use it but it keeps crashing

If you expect proper help from people that use the software and wish to get that assistance please provide more details on the situation and what you currently are trying to do... maybe some screen shots etc will also help show the problem. I have never had an issue with OBS, and most issues are actually user errors.
