Howdy! I have a huge problem I was wondering if you all could help me.

I have been USING Movie Maker for some TIME now and while it has GIVEN me a fit here and there, generally it is fine. Well, recently, it has been really giving me fits. I do videos on YouTube and I usually record in 60fps. When I had started, MM was fine with it (I had actually set Fraps to record in 120fps for best results, as suggested by a friend, but the videos were published at 60fps). But now, if I load ANY 60fps footage into it, it severely hiccups during playback and EVENTUALLY crashes. This makes editing a chore. I have tried everything, but to no avail. I have uninstalled/reinstalled, updated, everything. Now, it will only accept 30fps footage with no issues, but I fear that it might end up giving me fits again. I would love any help to get this fixed.

I know that I should get a better editing program, but that is not an option right now has my budget is VERY TIGHT, so for the time being, I would just like to get MM fixed and worked at full.
