"Start Searching Button" will not get enabled?

[eduardofox2]

After hours of importing the latest UniProt database, I now cannot search the test .mgf file that came with my MPA fresh install. I am on a Windows computer, and this is my first experience with MPA.
Does anyone know what is missing, or whether this is a software error?

Thanks

(I just noted that the "Settings" button will show nothing -- not sure if this is part of the issue.)

It could be an error in loading UniProt database. I have pasted an error as below.
