Problem with loading Assembly at hosting (Minecraft)

Guys really need your help with the server load on the hosting already 3 day I suffer. The point is you can't put the Assembly with the mod on the server (minecraft version 1.7.10). After reading other forums I realized that spigot, craftbukkit is not currently explicitly support fashion and are used more often on servers with plugins. I decided to use the so-called KCauldron.



I bought hosting for the website craftbuy.ru (not advertising), the service itself was not very arranged, because that's where my question couldn't answer and sent it to the forums that I did. In General, the core server on this hosting is taken from the jar folder in the main directory of the server, but somehow magical and it is not clear to me is the way reads only the usual zapuskaem server (minecraft_server.1.7.10), but if I put (cauldron-1.7.10-1.1236.05.211-server), it just refuses to start

I want to add that all data in the file (server.properties) are correct and (eula.txt) the paragraph of the eula equates to true.



The huge request to help you just before a server is very easy to put on hosting, but haven't done it in 2-3 years, thanks in advance to all who respond.
