I have had the same issues with 6.0.1. Probably best to just avoid the update unless it has something you really need. I think even after the error, though, my acrobat now reads 6.0.1.
see the whole thing is my acrobat isnt working at all now, so i'm thinking the update would fix it but its not letting me upgrade or even start Acrobat. Its saying that i have a problem with the language resources but Acrobat is set to english and so is my mac. if it wasn't for Photoshop, Illustrator, InDesign, and GoLive, and Premire i would hate adobe..
