Hi. I'v e been trying to render about an 1:30 long video, but it keeps getting stuck on a part with audio FX. When i pre-render the part with the FX, all of the FX in the video disappear in the final product

Oh sorry, forgot to mention the software.

The rendering problem appears on Sony Vegas 13.

I'm using an older ASUS a53s laptop, with upgraded memory:

Windows 10 64-bit
Intel Core i7-2670QM 2,20Ghz 4 Cores
8GB DDR3 Ram
440GB HDD
Nvidia GeForce 610m
