Vegas Pro Freezing When I click "Render As"

[ArcherLegend]

Hi guys so I'm trying to render a video but whenever I click "Render As", my Vegas freezes and I have to close the program. I tried reinstalling it twice and spent hours trying to find an answer online, but I had no luck at all.
Any help?

I already fixed this issue by just upgrading to Vegas Pro 15, which I don't really like, but thanks anyways!
