plugin caused a 310 error to my admin

after I updated impact to 1.5, it caused a 310 error (too many redirects) to my WP dashboard and I could not log into my blog until I had my webhost help me out. The impact plugin is deactivated until further notice. I am afraid to delete and reinstall as I really dislike not being able to get into my admin. ??

I had no issues with any updates before the 1.5 version if that helps.

I look forward to any fixes as I do like this plugin.
