For the past few days, even before an upgrade to 10.4, I get an error when I try to start Acrobat Pro, but not Distiller. The error message says there was an error with the Comments plug-in, Bad parameter. To get Acrobat Pro to launch I have to Get Info on it and disable the Comments plug-in. I have tried running the 7.0.1 updater again but it says the installer won't work on the version 7.0.1 I have installed. I tried reinstalling the 7.0 version but it gave the same error even before trying to update it. Right now I am at a loss. Any suggestions?
