Hello everybody.

I'm quite new on the PD world and I've been working with square, saw, and triangle waves that use the expression object to set the equation for them.

Although at first it worked, a few days later when I went back into the patch all of the expression objects were no longer recognized (they were red) and it says it couldn't create.

It happens to ALL of my expression objects in all the patches in my abstraction folder (and beyond).

Does any of you experienced this or have the solution for this issue?

Thank you in advance
