I got the free upgrade to TI 9.0 since I purchased TI 8.o on Sep 17th... First, if I download the latest update file, build 2259, is that a fully installable file? The web dwnlad page has the update, but also has a choice for Download Installation File. Do I need the installation file? I thought the update file was a full version - judging by the size I'd think it was... Any input? And... I am quite content with 8.0 for now -seems to do whatI bought it for. Should I wait to upgrade (some of the new features sound useful) until some of the problems ssettle down? Or are the problems overstated as this is a place where people come for answers?
