Hello, that's a strange one!?
Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
I repaired permissions on safe mode and it still is not doing it for me.
When I am on the log in screen, the wacom tablet seems to be working normally, but when I log in to my account, it stops working and need to reinstall in order to be able to use it.
I only have one account on my mac and it is admin.
Any ideas about what could be happening?
I was cleaning up my mac recently, and I may have deleted some file accidentally.
I reinstalled mavericks yesterday, and the wacom tablet is still giving issues.
I have an intuos 4
I'm having the exavt same issue as etirado01.
I tried the safe mode/repair permissions fix a handful of times and this issue has been happening with 3 different Wacom tablets for about a year.
Still no progress?

I was having the same problem with the wacom driver, had to re-install it everytime I reboot,
then I went to my Clean My Mac and noticed in the "login items", the "com.wacom.wacomtablet" item was disabled. So I enabled it, reinstalled the wacom driver again, and it's all ok! the "com.wacom.wacomtablet.plist" file is located in the "Mactintosh HD/Library/LaunchAgents" folder.
I might have accidentally disabled with Clean My Mac,
but if your Wacom driver's having the same problem and repairing permissions isn't working for you, try restoring this plist file. Hope this helps!!
