Hi to all!

An FTP application I've been using for years... I used it yesterday without any problem.

Suddenly this morning, when I tried to open it, I got a message like this from the Finder (just another application, I took this image on the Web). Since then, nothing is happening when I try to open it.

I tried to download the last Mac version of the application, but it seems I can't install it. I don't have the proper OS version.

Extra question: Apple is not offering me an OS update... iMac is too old? Mid2011.

I tried with a TimeMachine backup of the application, not working either.

I'm confused... how can this happen when I did absolutely nothing.

Thank you!

What OS version?

Also, what messages are you seeing from the program in

What you've provided, no real information to go off of. Eg. might have some corruption, missing library, other.
