When I try and load pre-sets I often get a message saying there's no disk in the drive, please install a disk in drive J. Drive J is part of my card reader. I don't get it, anyone else see this?

Maybe search registry (Regedit, then CTRL+F, F3 for next search) for "J:" and see if Rapture Pro comes up  (in HKEY_LOCAL_MACHINE).

Rapture Pro??

I have not.

I mean zeta not RP sorry. Brain fart.

I haven't found anything and I'm thinking Z3ta is just buggy.

If you are using the load option from the Program button, this opens a Windows file dialog which points to the last path opened by the dialog. The path may have nothing to do with z3ta+2. I keep all presets within the z3ta+2 programs tree and use the program browser to the left of the Program button.
