Sony Vegas 13 Crash

[SkellyBot]

Hey,

I recently began using Sony Vegas 13 and I've been having an issue with it. Whenever I put a big file into it, it crashes. I was able to put a small video into it and it works, but then I try it with the 25 minute video into it and it crashes. It freezes and says Not Responding and then completely crashes. I've looked this up and I haven't been able to find anything that worked for me.

Also, my bad if this is in the wrong area to be posted. First time posting on here.

Thanks in advance.

Check the extensions of the files and if you have the proper codecs for those specific files.
Google how to find these if you need more help
