Hello Raster

I was mining from pool and wanted to try out the cluster mining but its not working I think. I have paste this in my .bat file -> hodlminer.exe -a hodl --url=http://roi.hopto.org:23110 -u mine -p miner -t 4 --coinbase-addr=RPbVMGKcipUtjdWNMwRhQEJUvyAsCmwQT3 -P -q

but it showing these weird things over and over -
