I'm getting the "Licensing stopped working" error whenever I try to open any of my CS3 applications. I looked at the troubleshooting steps here: Error "Licensing has stopped working" | Windows. I downloaded, extracted, and used the fix, but it didn't work. I tried looking for the FLEXnet service to manually activate it, only to find my computer devoid of said service. I'm assuming this is the problem, but I'm unsure as to how to fix it. I'm going to try redownloading the fix, to see if that will help. I await a response, thanks.
I would suggest Section 8.
Go with the complete uninstall/reinstall.
It's a pain,but nuke and pave works best. Follow the steps and have your serial number and discs at the ready.
