re-install of DS4 won't accept pro serial #
![BWSman](https://hpclscruffy.daz3d.com/forums/uploads/userpics/700/nD0E002C16BBF.jpg)
I recently re-installed DS4 (4.0.3.36) and when I try to put my Pro serial number in to activate the plugins; the OK button gets greyed out.
All the other plugins seem to be activated.

Are you certain the main app itself is registered with a Pro serial number? go to Help > Register DAZ Studio and enter your 4 Pro serial number there first maybe.
Doh; I forgot about registering the program itself.
Well, that didn't work. As soon as I pasted the serial # in; the Accept button became greyed out.
Sounds like you're not using the correct Serial# then.
It should start with "SDZSPRO-040" if you paid for it, or "SDZFPRO-040" if you got the Free Pro version.
Downloading the latest version of DS4 solved my problem.
