hi there,
first of all thanks for the taking the time to make a nicehash clone for MPH.

I tried twice to mine with it but it failed the 2 times.

1. ran the benchmarks + checked the start mining
when I came back after an hour, the app had exited and nothing was running.

2. ran the benchmarks alone, as I thought maybe the 'start mining' option wasn't working properly
when I came back an hour late, the app had exited too.

I am running this on a dell inspiron 5675, CPU =Ryzen 7 1700X, GPU = radeon rc 580 8GB, windows 10 home

When using multipoolminer scripts (https://github.com/MultiPoolMiner/MultiPoolMiner) it is working.

any ideas why it is not working with your app ?
