Export midi filed won't let me save??

When I select export midi file it take about a minute to load to the save screen and when I click save it won’t do anything??

Just updated to 7.5.10 but never tried this in 7.5

I was able to luckily copy and paste to an empty project. I think the projects from cubase 5 get corrupted in cubae 7.5.

Got it done anyway.
