Fmod studio project crash.

I’m implementing sound fx for my project and decided to use fmod studio.
Everything went fine. Made few event sounds called them from scripts. Very simple stuff.
Next day for no apparent reason I cannot open fmod project file.
Every time it crashes.
Is this a common thing ?

Now it’s not a problem i can redoo all the work in no time but when the project gets bigger/more complicated this becomes a huge concern.

I’ve got response from fmod programmer. It appears the master bank was missing. He offered help to fix it but I already redid the project. Learned one thing though. The fmod tech support is awesome. Considering I’m not even a full fledged consumer ( don’t have license yet) and they offer to take the time and fix the project is very reassuring.
