As an alternative, you can use a simple program called SASHIMI... it is free and works really well.. there are many different video tutorials and a documentation explaining how to fully use its available features.. it automatically generates an xml file for you email accounts, and lets you easily pick which cabs you want to install after reflashing..it also has many other advanced features and can do everything you can do with UC, except more... i really like it and if some of you guys are having trouble with UC, you might want to try SASHIMI.. it can be found here:
