I ctrl + click the .iso files to open with Toast Titanium 7.0.1 and attempt using the interface to "Mount", but nothing happens. I enter the "Utilities" menu and select "Mount Disc Image" to no avail. The error message that shows up is: "Couldn't complete the last command because of a Mac OS Error. Result Code = 192"
Huh? Anyone else have this problem? I tried using the ToastMount software as well, but that seems to make things worse. I am using an Intel MacBook and running the latest OS X (10.4.8). Help! Thank you.
