Mathcad Prime 2.0 crashing on startup.

Hi.

I am in highschool on my 10th year and we use mathcad as a standard program in math class, and without it, I am doomed.

Problem: Every time I start up mathcad, it crashes instantly.

It worked two weeks ago and since then I've tried reinstalling it, then running it, it crashes, reinstall it, repeat the evil cycle.
