Seems like the Library at github.com/conformal/btcutil changed something.
First off,   "github.com/btcsuite/btcutil" seems to be correct now, but then again its not working.
Can you confirm that this is working just this way for you (on windows?) I know, windows sucks, but
as i said im not a programmer so i have to work with what i have

Edit: concrete, i get this error:
.\test.go:12: undefined: btcutil.Base58Decode

Edit2: If i change "btcutil.Base58Decode" to "btcutli.DecodeWIF" I get the error
.\test.go:12: multiple-value btcutil.DecodeWIF() in single-value context
