Can't detect nor install CGMiner

[SuperIsakSwahn]

I have cgminer in literally the same folder as multimine but it detects ''no copy of it'' and when I try to get it to download automatically it says something bout ''value may not be null''

I am having the same issue,
I am running windows and after installation, I am asked to download BFGMiner. After clicking yes it throws an exception error:
value cannot be null
Parameter name: uristring
I am guessing this is because the download link for BFGMiner is broken, I manually downloaded BFGMiner into the Multiminer folder but this does not fix the issue.
