To those having the same issues.
Right click the persona files you wish to add into the sever editor before adding them in, click properties of those two files, see if they are blocked by windows and if so, unblock them and click apply, then add them into the Server Editor.
example:
As you can see, windows blocked the persona I DL.
It seems to be the most common problem people are having with the Server Editor.
Windows tends to block files DL, and one must unblock them via the method I explained.
It is a must to run everything by right clicking first, making sure it is not being blocked by windows, then upon running the programs themselves by also right clicking them and run as admin.
