Additional problem #3. How do I become a "plus member" to pay for some additional templates??
With versions earlier than 11, there is no more Sign In. If you get any message to that effect, ignore and cancel out of them. You should be able to move forward to your import, editing, and exports using the program nonetheless.
As for the disc menus, those marked photoshop.com plus members only are no longer available to you in versions of Premiere Elements earlier than 11. You may see the thumbnails for those members only items, but they are no longer available to you in Premiere Elements earlier than 10.
Interestingly, many of them are found in Premiere Elements 11, 12, and 13 as part of the program with no need to purchase them or have any special membership in anything. Adobe has promoted Adobe Revel as a replacement for photoshop.com, but that has no impact on this disc menus issue.
This all has to do with Adobe discontinuing photoshop.com and photoshop.com plus et al.
If you need to download regular disc menus for Premiere Elements 10, please review the following
1. No more Sign In for Premiere Elements 10
2. No access to photoshop.com plus (members only) disc menus
Any questions or need clarification on anything written, please do not hesitate to ask.
