If you go to the license center in WCS, do you see a total of 200 AP support. You need to make sure you have a base license before you add additional plus license. I had an issue before, where I added a whole bunch of plus license after I installed a 250 base. I had 400+ APs and ran into the same issue but I had 250 base. Well I forgot to add the other 250 base so I had to remove all the plus license before I could add the other 250 base. Then I had to add all those plus license after that. The license center will tell you exactly how many APs it will support. From what you posted, it looks like you have 0.
