Upon installing the 30 day trial of Arc10 I accidentally clicked the radio button next to 'concurrent use' instead of 'single use' and I need to get back in to select the single use option.  I cannot uninstall and start fresh becasue windows installer will "not respond" and freeze the uninstallation process.  Is it possible to change this?
