Error when joining a LAN room

[N-Zocker]

When trying to setup a LAN room for the Oracles Multiworld I get the following Error: "Error in Listen: ...\Downloads\BizHawkRoot\bizhawk-co-op\sync.lua:49: bad argument #1 to 'lines' (bizhawk-co-op.lua: No such file or directory)" for the hosting side and: "Error during Join Server: .\bizhawk-co-op\sync.lua:49: bad argument #1 to 'lines' (bizhawk-co-op.lua: No such file or directory)" for the joining side.
