I'm sorry you're experiencing this issue! It sounds like it's an issue with Pokki which is used by Instagrille. Did you try restarting your PC?

Glad you like the new version! We would love to allow users to upload photos from Instagrille. Sadly, we rely on Instagram's API and it does not allow us to do so at this time. Hopefully this will change in the future!

A Mac version will be released next month!
