I spoke to Adobe, they let me redownload an updated version of CS5 which did not work, I still cannot upload and they said that there was nothing they could do about it. The tech said I should post the problem on this forum and maybe someone has a fix. At this time I still cannot get any updates and I have heard from no one else. My feeling is that this is their way to get us to upgrade and get Photoshop CS6, but that is me being my cynical self. I have tried downloading the updates every time I get a message that there is one, but it never works. Good luck and if you ever get a fix, please let me know.
I just got an update message yesterday, I will try again when I have time.
