I'm trying the x13 algo with sgminer 5.0, but with the following command line, my prompt window is closing on startup.

setx GPU_MAX_ALLOC_PERCENT 100
del *.bin
sgminer -k marucoin -o stratum+tcp://stratum.nicehash.com:3337 -u BTC_ADDR -p x -I 13 -g 2 -w 256 --thread-concurrency 8192 --api-listen --api-allow W:127.0.0.1

**even the marucoin-mod is doing the same thing.

Thanks for your help
