Hi, I installed Active Sky after long time. I bought my bundle Active Sky X and X Graphics in 2007. I read that I can upgrade to the version of Active Sky Advanced and after next version Active Sky Evolution. I cannot download the update to ASE. Unfortunately, I cannot find the update from the ASX to the ASA. well understand I that I must proceed update version step by step ASX to version ASA and next to version ASE? On your website i cant find update Active Sky Advanced from Active Sky X...only update ASA to ASE. Links from main screen in program Active Sky X do not work. When i click to links, displays webpage that does not exist..I cannot download SP4 for ASX or upgrade ASX to ASA. How do I upgrade from Active Sky X to latest version? Thank you for your help. Sorry for my english.
