這問題很帥....
主要就是Steam上的Skyrim SE 更新了 1.5.16版本，結果使得 SKSE64 2.0.4不能用了，因
為版本太新。
SSKSE64 2.0.4版的版號是對應 Skyrim SE 1.5.3版的。
我查了一下才找到國外有人找出解決方法。

SKSE64 FIX
Spread these steps! That's how you solve this nonsense. Show them!
1. Start by pressing win+R, and then pasting: steam://nav/console
按 win + R 叫出執行視窗，執行 steam://nav/console，叫出 steam console。
2. A steam console should appear now, just paste the following line:
download_depot 489830 489833 911281757511576655
在 steam console 中輸入指令 download_depot 489830 489833 911281757511576655
3. The v1.5.3 exe will downloaded to
[...]steamapps/content/app_489830/depot_489833
steam會下載 SkyrimSE 執行檔 1.5.3版 到：
C:\Steam\steamapps\content\app_489830\depot_489833
(當然每個人steam裝的目錄會不同)
4. Just go to where the exe was downloaded and paste the old exe inside your
root skyrim folder replacing the "new" one.
把 SkyrimSE 1.5.3版 複製貼上到你的 SkyrimSE 根目錄下取代 1.5.16版。
SKSE64 2.0.4 就能用了。
