That's the message that popped up earlier this evening when I tried to open iphoto. It goes on to say, "Please quit and upgrade this library by opening it in iPhoto 2 or iPhoto 4." The specs: ibook G4 1.33 (the last one) OSX 10.4.9 (I just updated from 10.4.8 to try to fix the problem) iphoto 5.0.4 (I don't know why I missed the last couple updates- they just never popped up like itunes and OSX updates. I tried installing the latest version of iphoto (6.06), but it won't let me do that since I don't have 6.05, which requires 6.04, etc.) Also: My iphoto library resides on a lacie external hard-drive. This has never been a problem before. Any suggestions? I'm counting on you guys! UPDATE: When this problem started, earlier this evening, everything else was working normally, but I just went into a file on the external hard drive and it started spinning noisily without bringing anything up. I had to relaunch finder to get it to stop "wonk wonk wonk wonk"ing. I ejected the drive, turned it off for a few seconds, and plugged it back in, only to get a message that the computer couldn't read it. I repeated this after restarting, with the same results. Then I tried again a few minutes later, and everything worked fine, except that I think some of the files were missing from some folders on the HD. Then it started making the repetitive wonking sound again, like it was stuck in a rut, and when I ejected, turned it off, waited, and plugged back in, it said that it wasn't readable again. I don't know if all this is related, but it sure is weird that after months and months of trouble free macbliss, I should suddenly have a bunch of problems all at once. It's definitely making me suspicious of the Lacie Hard Drive. And just when i was about to buy another one!
