Ok I am still having issues... I have tried the auto-update inside the MS folder and after it is done it starts the page white page with the circle status in the bottom right but doesnt actually open a miner?
I have since deleted all MS files from my computer and downloaded/re-installed fresh 2.9.1 and it is still doing the same thing?
Similar thing happened to me few weeks back and I found I was incorrectly using all caps for the miner type in the config file. Has to be lowercase and make sure there's no typos. Just one character off and it won't open anything. Check README in MS install directory for exact guidance.
