I'm missing something on an old installation

I've got some old projects that I'm attempting to do modifications to on a timeline so I don't want the pain of porting to modern environment.  I'm running SSP 1.7.5 and IDE 7.8.0..

My problem is that I moved machines some months ago and I must not have gotten everything moved.  IDE runs fine but I can't compile some things.

I can open the sf_touch_panel_i2c.c file (which shows protected watermark) and can compile it no problem.

Anything in that dave2d directory I can't do either. Opening the file in the IDE gives me: "Decryption not permitted file: blah blah blah"

I don't know what I could be missing if I'm having an encrypted file like the touch stuff compiled but not the dave2d stuff...

Any hints at what file I must be missing?
