Cant find /~ (div~) in 10.4.6

Hi list.

A colleague of mine cannot use my patches which include the
[/~ ] divide tilde object. (div~ also not working)

• error: can't fragload /~ (missing <>), err -2804

We have reinstalled Max4.5.7 twice now.

I am currently using ducttape and the [/ 1.] object to keep our patches
working...

Would be nice for the tilde version to work...
