icons gone stupid..

after formatting and reinstalling last night everything is so much faster :) windows boots & shuts down faster, whichs is nice, but i installed a couple of programs - winRAR and Alcohol 120%, and now all my rar/tar files have Alcohol icons instead of winRAR ones.. i downloaded tweakUI and did rebuild icons, but that did nothing, and now when i click on the 'new' tab of tweakUI it gives me an error and closes...

any way of making my icons be the ones they should be?

cheers
Mark

edit :
winRAR still has file dependancies etc, if i double-click a rar file it opens in winRAR, just the icon is of alcohol 120% :(

zip files still show with a winRAR icon, just rars and tars it seems...
