My hard drive died and I has to completely reinstall, including Adobe CS5 Extended suite. Before the crash all was working well but now I get a message from AAM that Adobe Pixel Bender Toolkit 2.5 Update failed because "There was an error downloading this update. Please quit and try again later." What can I do? I am on Windows 7 with all updates and my CS5 is fully-updated apart from this.
I had a similar problem after reformatting my hard drive and doing a clean install of Windows 7 and Adobe CS5, although for me, I was having trouble updating the entire suite.
The solution was to update the AAM first. See this thread (especially the reply by natewinck on Aug 20, 2014 7:52 AM) for the solution details.
However, I was still having problems getting the PixelBender 2.5 update to install. Turns out this is another known issue that needs a hotfix installed first.
Hope this helps.
Brilliant. I set my clock to 1/09/2011 as the thread you posted suggested and it worked. I was having trouble upgrading the whole suite as well, but found the upgrades for the rest of the suite manually. This was the last bit.
