Default Hardtop stuck partially open

I stopped the opening of the top partially opened in order to glue the headliner. Now it does not move. I tried the procedure in the manual of holding either button down for a minute and I also tried disconnecting the battery. Here are the messages and the results of the scanner. Any suggestions would be appreciated:

After starting engine = “roof not locked”
After pushing up or down button = “roof failure see manual”
After holding down button for 30 seconds = “roof failure service required”

Default Fixed

FYI - I got it working again. I tried to jog the CRM brain by driving it a few feet until the warning chime started. But that did not do anything. Then I reached into the trunk and loosened the plastic divider. I started the engine and pushed the down button. The message about a loose divider appeared. I reached back into the trunk and closed the divider. Then I hit the down button. It started moving but only about halfway down. Then I hit the other button and it closed all the way. Then I hit the other button and it went all the way down this time.
