I've got Vegas 14 on steam, and its been working great, a few problems when reinstalling steam and reinstalling the software, but after that it was easy to edit anything. so far, ive only edited things that were max 7 minutes long and never got any issues. but now, ive got a 12-13 minute video and a fair amount of text media in it, as well as lots of splits etc. it crashes non stop, no matter what. ive finally edited it so it looks acceptable, but it keeps crashing and interrupting my renderings and my editing. is there any way to make it so vegas wont crash from editing these clips?

• I use Windows 10 64 bit
• 16gb ddr4 2133
• 450 gb storage left, previously 1tb
• 1060 3gb gddr5
• intel i7 6700k (not overclocked)

please help asap!
