Adobe Download Assistant, Photoshop Elements 11

Altho' I've tried many times over the past few days, I've been unable to download Photoshop Elements 11 using the Adobe Download Assistant.

I received an email from Adobe inviting me to download Elements 11, with a key to convert the trial version to a full version, which is an upgrade for me.  I think this is because I wa never able to download a workable Elements 10.  It constantly crashed, and sometimes brought my computer down with it.

I'd love to do download a working version of Elements 10, and have spent many hours trying, but nothing ever results from the Adobe Download Assistant.

Now it's telling me (in tiny grey letters on a black background) "The download product installation appears to be corrupted.  (Error 108)  Use the 'reset product download button' to try to download it again."  Unfortunately, there is no reset product download button to use.  I have clicked on a down arrow which produced a selection of whether to restart the download or continue trying with the download already started.  I've chosen to restart the download.  Unfortunately, nothing has changed on the window, and it is still telling me about the corrupted download.

I have no idea what the next step is or where to go to determine whether this whole thing is a hoax or whether it will download Elements 11.  If it does, will Elements 11 work?

Can anybody out there help?
