I have installes the newest Version of Little Tiles and the newest Version of Crative Core
here is the error code:

Error: java.lang.NoClassDefFoundError: com/creativemd/creativecore/core/CreativeCoreClient
Exit Code: -1

Download LittleTiles from Curseforge only.

latest.log
this is the log file

I downloaded it from Curseforge lol

The filename suggest otherwise, just update CreativeCore and LittleTiles from curseforge and it should work just fine.

Hmm okey
