What's Wrong?

I am a pro user. Claude addin to excel works. Claude addin to powerpoint however, does not. After i add the claude addin to powerpoint, i try to login and then the problem happens. The addin always says ... error, the code is too short, try again.... while the code is the exact digits claude gives me.

What Should Happen?

Claude should log me in to the addin for powerpoint use.
