Error: failed to load the voice database

So i just started up synthesizer v this morning and everything seemed fine, but when i try to open any of my project files i keep getting the error “failed to load the voice database - there could be a version mismatch or data corruption”, and i am unable to play my file. Whenever i try to put a voice for any new file i get the same error. I am using the current version of Synth V so how do i fix this?
