Hi everyone I recently acquired an 5000D and it works perfectly until I turn on the clicker. If I turn on the clicker the line guide stops moving. I can take it apart and reset it and it works perfectly until I slide the clicker on then the line guide stops moving? Any thoughts?  I'm thinking I must be missing a piece. Thanks for your time in advance.

Take the left side plate off,and push the clicker to the on position. If anything is touching the cog wheel,that's the problem.
