I can't import aia files anymore!

I just can't import project (aia) from my computer. A window comes and says "I can't have any spaces or disallowed characters". The thing is I use to be able to import projects til one day I must have changed the file type used to open the file, which doesn't make sense cause all the files that I am trying to import all end in .aia.

--

just rename the file before importing it... use simple names without spaces or special characters, for example mark.aia

Thanks so much! That was it :) I don't understand why it wouldn't work with spaces but that was the problem, whenever the computer makes a copy of a file it adds (1), (2).... This problem should be told to other developers just getting started.
