Upon opening Houdini 14, I get this message:
And indeed cannot get the handles show up.
Did I make a mess myself and how to fix it?

Thanks, Robert

EDIT: I also noticed that some of the other SOP's stopped working properly. :shock:

Ok, I solved it by deleting the whole Houdini folder in User/Documents
Don't know why and how this happened, if someone is willing to shed some light on it, I would be even more happy.

Thanks, Robert

This was likely caused by attempting to overwrite a factory node type, in this case the Add SOP, with a digital asset definition of the same name. To avoid such problems in the future, you'll want to put your digital assets into a custom namespace.

In short, if you have OPcustom.hda, delete it.
