Here's one that not listed in the first post.
On the My Accounts page, the following products have a 9 digit serial number (XX-XXXXXX). These titles fail the Activation step.
SkinStudio 7 Professional, DeskScapes 3, DesktopX 3, Fences® Pro, IconDeveloper, IconPackager 5, Keyboard Launchpad, LogonStudio (Free), SoundPackager, Theme Manager (Free), Tiles, Tweak7, WindowBlinds 7, WindowFX 4
I have emailed support and for the second time got a canned reply to go to My Accounts page and use the serial numbers supplied. This is not helping me.
