It's pretty clear you're not a developer (or wouldn't be for long).

There are two really bad decisions here:

1) You are driving away up to 15% of people who actually use your product. How much would you spend to acquire that many active users? It's easier to keep existing users than acquire new users.

2) Sending users through a ticket system for errors you could have prevented with a simple warning is a bad experience for them and far more work for you. And most users will silently disappear instead.
