I try to modify xoopsfaq module to a module named "faq". The trial is failed.

My modification: I copy the original xoopsfaq and change to the name "faq", change the tables' names and templates' names. Then I upload to the module folder. After press installation button at Admin System Modules, no tables are created. But there is a blank box added in the Module Install Area of Admin System Modules. There is no name appeared of it. I want to uninstall the module by the uninstallation button in the Admin Sytem Modules. But it says "Module File for Not Found", it fails to uninstall the module.

What can I do to delete the failed module as it is no name? Can I do it manually? How?

Thanks in advance!
