About the Problem in desk login

Recently i had created one Custom Doc Type and saved in module of school, after that i got server error, then i had log out from my profile, when i again tried to login i got the error " 1146, “Table ‘24e45afd7c84bf02.tabPost Placement Feedback Form’ doesn’t exist”. after that i am not able to access my Desk and other apps. here i am attaching the screenshot of the error page.

Please tell me how can i again access my module.
