Problem z pluginem skript!

Witam! Skript nie czyta mi żadnego skryptu nawet tych najprostszych typu

command /regulamin

      trigger:

                send i tam cos tam

Wiem ze sa wymagane dodatki typu skquery, wildskript jednak gdy je insstaluje to nic nie pomaga. Skrypty dzialaly na moim starym serwerze. Serwer 1.8.3 spigot, mam skrayfall wszystko ok. Skript robi taki error:

[Skript] Enabling Skript v2.2-dev37c
[21:23:39 WARN]: [Skript] Using this version of Skript on 1.8 is highly discouraged.
[21:23:39 WARN]: [Skript] Some features have been disabled; use older Skript to restore them.
[21:23:39 WARN]: [Skript] Also, there are probably bugs. And since 1.8 is not supported, they will not be fixed

Jak pobieram inne wersje z https://github.com/SkriptLang/Skript/releases

21:42:52 INFO]: [Skript] Enabling Skript v2.2-dev15
[21:42:52 ERROR]: Error occurred while enabling Skript v2.2-dev15 (Is it up to date?)
