Do you want help with that "problem"?

the video lag problem for sure

There is a new build/update available. Please see here

(If you use Chrome to download and that does not work, try a different browser.)

Lagging can depend on your used sourcefiles, your used projectsettings, your preview settings or maybe rendersettings, but for sure on your used hardware as Processor, possible GPU, needed Memory and store locations.
None of those we know, look here what and how to provide: https://www.vegascreativesoftware.info/us/forum/important-information-required-to-help-you--110457/

video lags soon as I put it in timeline &preview -even before rendering so that would be sourcefiles or preview settings?
-only started using MS17 last couple months
-first video I ever made had no lag at all & don't feel like I've changed any settings

was also told that maybe I need more Ram idk

so safe to say there's no solution to video lag???

Some of the options mentioned in the link above are not available in your VMS, some are. Note that e.g. to change Preview Quality, you need to right-click on the Preview window to find the relevant menu.

Ok now I have another problem

Transferred a video I made w/my phone to a file on the computer but when I brought it into MS17 the video would play but the audio would not

Is there anything I can do about that?

None of those seemed to make any difference
-would uninstalling &reinstalling make any difference?
