PHPStorm unusable after crash

Question

Today PHPStorm crashed out of the blue during some Javascripting.

After restart, nothing works: I can't open preferences nor files.

Files are no longer associated with Editors:

I restarted my MAC and have reinstalled PHPStorm - no luck. Since the latter did remember my registration details, I assume I missed something on deleting PHPStorm.

I have absolutely no idea what to do now.

Most likely configuration/plugins files are corrupted, you can delete or rename the following directories to start with the defaults:

• Settings: ~/Library/Preferences/WebIde50
• Caches: ~/Library/Caches/WebIde50
• Plugins: ~/Library/Application Support/WebIde50

Other users with similar problems on another systems or with different IntelliJ IDEA platform based products can refer to this document to find the location of these folders on their system.
