Seemusic so slow and animation not there after rendering

I have just purchased Seemusic to animate a simple melodic exercise. The midi file is about 3 min long (fl studio midi file).

After setting it up in Seemusic, I have tried rendering it twice, and both time it took about 2hours to render and then the animation is only on the first 2 notes ?!??

I have not touched rendering setting it’s pretty much as defaults would be...

Help!?

Note : 3.2 GHz Intel Core i3 with Sierra + very latest seemusic purchased it yesterday.

Here is the midi file (there is only 1 midi file) and I already trashed the animation done after purchase, but I have the first rendering (before purchase with watermark) took 4 hours to render and you can see the animation is only on the fisrt 2 notes but for some reason here it uploads up to 99% so I can't show it to you :(
