The Esellerate website address to get other copies of email receipts that have been lost, is listed on 3 different places:
- The install guide ( named fsdt_install_guide.pdf, under the fsdreamteam folder )
- The FAQ page on this website
- The sticky thread in this section of the forum, aptly named "Reinstallation after system upgrade or crash, please READ!"
The Stand-Alone Addon Manager at the end of all installs, is required to update sceneries that might have been updated after you downloaded their installer, so you don't need to download their full installers again.
So, it's required in your case, unless you re-download everything. In any case, you WILL get a message suggesting you to install the Stand-Alone Addon Manager, in case you need it.
