Hello, I have a problem with installation of my custom module to one of my sites. I have installed it into a few sites and had no problems with that, it worked perfectly, but with one of my sites I don't know what I've done wrong. It doesn't work partially. When I add it to a page it looks normally, but the list of module settings is empty. And when I press some button of my module en error occures.

I was testing this module on local server and found that if I delete from the database tables that was created with "SchemaInstallScripts" and "SchemaUpgradeScripts" during the first setup, they do not restore after the second setup. During the first setup it sayed "Running script onlineconsultation..." and "Configuring module onlineconsultation...". During the second setup it says only "Configuring module onlineconsultation...", and it doesn't run scripts that created that tables. I tried to remove my module through administration->advanced settings->manage modules and it doesn't seem to remove it completely, because in the system information page it's still there, and after running setup again it returnes back as broken as it was.

Please explain how can I delete my module completely and then install it like it's the first time.
