I need to update my CE and I am currently running version 5.4.3. I tried downloading and install the current version from the website a few days ago and the update installed but did not work. 5.4.3 is still what appears on my computer even after restarting. Now when I go to uninstall and enter the uninstall code it tells me I need to enter a valid uninstall code. When I click ok to close this box in continually pops up again and again. I really need to update to the newest version because a bug in the old version is keeping my software from functioning properly.
