Yo dmedici,like crinina1 just mentioned try looking through your registery,but i see you are a AO newbie and you may not know how to edit/be convident editing the registery.If this is true try downloading a free registery editor like I use called regcleaner you can find it at http://www.jv16.org.Please bare in mind that even with a registery editor you should still be careful what you delete.But if you only delete regisery keys from programmes that you have already un-installed then you should be safe.
