Yayyyyy, thanks!A new version of Forwarder3-DS is now up in the OP. This once again, should fix support for the original R4. M3 Simply users, use the original R4 option for your forwarders.
Ignore the update prompt, because it hasn't been pushed to the update channel yet. If it's pushed to the update channel, @Olmectron should release a .EXE version, and I'll add that to the OP as well.
