I have been using AE on the 32bit windows7 for over a year. I had to reinstall my windows recently and therefore get back all the programs. When asking the customer care, apart from always getting disconnected, I couldn't find anyone to help me find the right version. I was told AE is only compatible with 64bit, when I know in fact this is not true. I believe I have been using AE CS4, though I'm not sure, how can I get help?
