My problem is with LR2 print module on a Macbook Pro (latest one), 10.5.4 and a Designjet 130. When I try to select "paper type/quality" from the third drop down box (that usually shows layout), "hp_designjet_pde" has a line through it and when selected LR says "the bundle could not be loaded because it does not contain a version for the current architecture". BUT it worked perfectly until three days ago and all other apps can see it and allow me to select paper type/quality as normal, including CS3.
That makes me think something has been corrupted in LR2, although I haven't made any changes anywhere. I have tried to uninstall LR by "removing it to trash", including any preference files I could find, then reinstalled, but same problem. Also, when I reinstall it, LR sees all my printing presets, and even repeats what I leave ready to print in the print module. So maybe I'm not removing the correct bit?
I have searched this forum, and Adobe's, but can't see the answer. All suggestions most welcome!
