I haven't touched anything after downloading the modpack from CurseForge. I am installing the suggested Forge version (on README.txt) from website, installing it after server is launched I am closing it and uploading everything from modpack to server folder (as it is suggested in README as well).
Thank you, I've remved AccessTransformer and REIPlugin. Now another error pops up on the console just as I start run.bat:
