I use AME every day in a professional work environment. Aside from slower rendering of AE comps than in AE, it works great, especially with Premiere sequences. Issues could stem from a few sources, old video card drivers, corrupted project, out-of-sync versions between Premiere and AME. I'd start with updating all the apps, video drivers, clearing the media cache, and restarting. If you're still having issues, could be a corrupted project. Try importing your previous project to a new one which usually fixes corruption. If it seems like it's from an effect, then try removing effects till it's working. These are the steps I usually take to identify where the problem is. Once you locate the problem, then you can start finding solutions. Hope that helps
