[Plugin: 7feedticker] Problem uninstalling

Just thought I should say…… I installed this plugin 7feedticker for RRS newsfeeds in my sidebar, and when I de-activated it, I couldnt get rid of it, I deleted it from the ‘de-activated’ list and deleted cache etc but still couldn’t shift it. I only got rid of it by swapping themes and swapping back again….when contacting the creator I was asked for my blog login username and password! err….no! Where do you rate plugins???
