I have just installed Flash Professional CS5 but the pallets & tools are greyed out and inactive.
I have tried re-installing the software but same thing happens. No error messages when installing. Other CS5 applications seem to be fine
I am quite new to Flash and am unsure what to do. I do have CS3 installed which works fine
I just had the same thing happen, and then I stumbled upon an odd fix:
In the top-right corner of the window where you can choose your workspace (mine is set to "Essentials" by default), use the drop-down and select something else. Then flip back to your preferred workspace. All my tools were then available again.
