Is it possible to have an import/export filter get corrupt?

Seems every eps I export out then import back into into cd X7 comes in as all one color. C0 M2 Y4 K92? Prints as full color though. Didn't have any trouble a few days ago. I haven't made any changes to the system that I'm aware of. Only the windows auto updates. Closed cd and deleted temp files. No help. Gonna try rebooting.

Import the same eps using another pc and it's fine.
