Activate license on cisco wireless controller

I have a Cisco Model 2504 wireless controller. I currently have 7 access points using the controller. I have purchased a new wireless access point, model AIR-CAP3702I-A-K9.

I purchased a license to add the controller. I added the license using the 'install license' command in CLI using tftp, and was notified the license was installed successfully.

I then restarted the router.

However when I connect the WAP to the controller with an ethernet cable it does not find the controller. The display light blinks alternately green and red.

When I use the show license all command, I see the following:

License Store: Primary License Storage
StoreIndex:  0  Feature: base                              Version: 1.0
        License Type: Permanent
        License State: Active, Not in Use
        License Count: Non-Counted
        License Priority: Medium
License Store: Primary License Storage
StoreIndex:  1  Feature: base-ap-count                     Version: 1.0
        License Type: Permanent
        License State: Inactive
        License Count: 5 / 0 (Active/In-use)
        License Priority: Medium
License Store: Primary License Storage
StoreIndex:  2  Feature: base-ap-count                     Version: 1.0
        License Type: Permanent
        License State: Active, In Use
        License Count: 7 /7 (Active/In-use)
        License Priority: Medium
License Store: Evaluation License Storage
StoreIndex:  0  Feature: base-ap-count                     Version: 1.0
        License Type: Evaluation
        License State: Inactive
            Evaluation total period: 12 weeks  6 days 
            Evaluation period left: 12 weeks  6 days 
        License Count: 75 / 0 (Active/In-use)
        License Priority: None

I know that the second to last is the licenses I was already using, and the last is the evaluation licenses. I believe the license I installed is the second one, which says license count: 5/0 (Active/In-use).

How do I activate this license? How do I make the wireless access point connect to the controller?

I figured out what is going on. I had purchased and adder license, but if you just install it it only installs as a base-ap-license, which isn't what you want. I needed to create a new base-ap-license at Cisco, according to the directions here:
