Adobe Acrobat Crashes EVERYTIME while I'm changing tools

This acrobat adobe is driving me crazy.

I study only for him, with my documents in the cloud, and ALWAYS, EVERY DAY, while editing and changing tools, he crash and I lose ALL of my editions because there IS NO AUTOSAVE IN THE CLOUD.

Please adobe, if it's difficult to fix these errors, please create an AUTOSAVE for documents in the cloud, I'm wasting hours and hours studying because of this.
