I got issues with reeorder.

Hi again just to reiterate what others have said thanks for this great module I’ve used it a couple of times on other sites and it all works great .. however .. I have installed 1.2 on a new site and for the life of me cant get it to work. It shows up in the modules but It does not appear to save any preferences, I also tried to uninstall it but each time I do this when I go back into the module tab it still shows as installed.? Sorry to be a pest but is there anyway I can remove all references to reeorder and start again? Ive tried all sorts such as deleting from my server and re-installing fresh copies etc .. I am definitely stuck. Any pointers ? thanks in advance.
