Having trouble launching Studio MX 2004 applications on Macintosh OS X 10.2.8 or 10.3 (Panther)? Get the Panther hot fix.
According to this Macromedia ServiceNote, this issue only affects users who upgrade to Panther. But take it from me, I installed the trial version of Studio MX 2004 on a brand-new PowerBook G4 with Panther pre-installed and was unable to launch any Studio MX 2004 applications. I kept getting prompted for my username, even when I entered it correctly.
Fortunately, Macromedia has released a Panther hot fix to address this issue. Simply download the DMG file to your desktop and double-click the unpacked installer. When the installation is complete, run one of your Studio MX 2004 applications. This time, when you're prompted for your password, you will be able to proceed to the trial or activate your software.
