what(): Type is not convertible to string

I have recently begun attempting to dual mine ethereum & lbry with the Claymore-Dual-Miner. Unfortunately, I'm receiving the following error when trying to run the miner with the following command line:

command line: ethdcrminer64 -epool us-east.ethash-hub.miningpoolhub.com:20535 -ewal xxx.desktopBOX -epsw x -mode 0 -dbg -1 -mport 0 -etha 0 -ftime 55 -retrydelay 1 -tt 79 -ttli 77 -tstop 89 -esm 2 -dpool stratum+tcp://us-east.luxor.tech:5555 -dcoin lbc -dwal xxx.desktopBOX -dpsw xxx error:

Does anybody have any experience with this error or have any pointers as to what I may be doing wrong here? I would greatly appreciate any assistance that you might be able to offer!
