A damaged or incorectly formated file

Running OS X - WaveLab 7.2.1
I get this error message when opening WaveLab 7.2.1:

This file is damaged (or it is of the wrong format)

Users/username/Library/Preferences/WaveLab7/Presets/Text-Variables/.last

After the error message appears, WaveLab shuts down.

Any help is appreciated, thanks!

Just erase that file then.

When I search for it, OS X says the folder can’t be found.

This is a non-visible file. You need to allow to show non visible files in the Finder.
