there is any way to remove the "missing logo.ico" error?
Create file "logo.ico" in GUIminer folder (copy bitcoin.ico to logo.ico, for example). Or reinstall GUIminer.
reinstall?

its its just a selft extract file, when i try to run it on new pcs it gives a missing loco.ico error, the loco.ico comes with guiminer and it its on the same folder.
