I purchased the Facetime app in the app store for my iMac. When it finished, I tried to activate it, but received a window stating, "an internal Facetime error has occurred." I placed the app in the trash, and turned back to the app store to reinstall it. To my surprise, the link did not say install, but instead purchase for .99. I really do hope a simple reinstall would not require me to re-purchase the app all together. Can anyone help me? Of course Apple's help would require me to buy apple care according to some receptionist... Thanks.
