Have been using Lightroom on my Apple computer for years. Now, ever since upgrading to Apple's Yosemite operating system I get an error message (150:30) every time I try to open a lightroom file. Has anyone else experienced this problem? Also how do I subscribe to Adobe's Premium Support? Every time I've tried (through contact support) I just get taken on an unending loop.
I think we need a lot more information.
Exactly what does the message say?
Exactly what files are you trying to open?
Exactly how are you trying to open them (what menu command or button or mouse action or keyboard shortcut)?
And lastly, what version of Lightroom are you using?
