I'm afraid that reinstalling thousands of templates is the least of your concerns
First, though, the "good" news: If any of the templates were included in past content packs, they're all available from the App Manager (assuming you have the subscription version), and they can be installed in one fell swoop. If you don't have the subscription version, the content pack installers should be stored wherever your downloaded programs are kept. You will need to contact Cyberlink's customer service if you need to get new copies.
Now, I can't imagine that you'd actually use more than a tiny fraction of those 3000 previously downloaded templates, but if they're not in a content pack, you'd need to download/install them one at a time. You can save literally thousands of steps by choosing
Run rather than
Save or
Save As from your browser, and this
post may help make browsing the DirectorZone website less of a headache.
The real problem though, is that PD assigns each downloaded item a numbered folder, based on the order each title, frame, PIP, particle, etc. was installed.
When you save a project using any downloaded item, PD simply records the numbered folder where the effect is stored, like C:\Documents\CyberLink\PowerDirector\17.0\MyPinPs\PiP_086.
When you reopen the project on the original machine (and haven't made making any significant changes to the system), everything works as expected. Same if PD is uninstalled and then reinstalled, and also no worries if you're only going to be using the downloaded content in new projects from now on. If the majority of these downloaded effects came from content packs, then reinstalling them should restore the same content/folder arrangement as before, and again you're in the clear.
However, if you've had to reinstall Windows from scratch, then unless you can install every downloaded item
in the exact same order as before, your existing projects will almost certainly have the wrong downloaded content applied when you reopen them.
That's because the content of the original "Title_267" folder might now refer to a title that used to be in the "Title_003" folder, for example. The timeline will be always be filled with the current content of each referenced folder, and unfortunately, I don't know of any way to determine what the original contents of those folders were other than by looking at the original videos that were produced.
If you need to edit an existing project, you'd then have to preview all of the relevent choices and then update each project with the correct content before making your new edits. It's a royal PITA
The best possible outcome is if you happened to have made a backup system image of your entire C: drive before you reinstalled Windows, because you'll be able to copy all of the relevent folders to the new installation, and PD will show the correct content whenever you reopen your old projects.
I hope you did that; OR that the vast majority of your downloaded content came from content packs; OR at least that you aren't going to have to go back and update too many old projects...
