So, Been doing some music with VST/Aria the last couple of months

2 issues

Randomly I will save a file and upon re-opening it, one or more of the instruments won't load, and I get silent music.  I have to manually go into Aria (or score manager) to reload a preset (or individual sound in score manager) to bring back that particular sound. Cannot understand why it is that the sound was loaded with the document, it will sometimes not re-load upon launching the file

Second issue. Volume of instruments. Having lots of trouble with this. Documents with NO dynamic markings. I will get much fluctuation of sound volume which I cannot seem to control and have to constantly re tweak in score manager. Why is this?
