Sudden crashes on every project in C10.

Am getting crash after crash on C10 on any project I work on, and it happens after about 5 minutes of working. This is the message:

“An unexpected error occurred. The system’s description is: Too many open files
No new project could be created.”

I already tried trashing preferences which did not help. Any ideas what this message means and what’s going on?

Pure guess : could it be to do with autosave?

Try doing a project back up to a new location.

Just tried. Backup Project does nothing – no window comes up, nothing.

Looks like something got corrupted in a Cubase presets folder for Retrologue. Weird! All is good now, thanks for the help guys.
