After restoring your Mac from a Time Machine backup, FotoStation fails to activate.
Using Time Machine can potentially break licensing for a FotoWare product. The problem is that Time Machine has backed up and restored a licensing data file that is not correct.
In Finder, press Shift-Cmd-G to go to a folder. Go to the folder /Library/Preferences/FLEXnet Publisher/FLEXnet and delete all files starting with fotoware. Do NOT delete ANY other files in this folder, if any.
Reset permissions on the /Library/Preferences/FLEXnet Publisher folder to allow your user to read and write. Apply these permissions recursively.
Reset permissions on the /Library/Application Support/FLEXnet Publisher folder to allow your user to read and write. Apply these permissions recursively.
Now try to activate FotoStation again. If this still fails, contact FotoWare Support.
