Can't access my cloud files after netcfg -d

Hello, I have a big problem.
I used the command netcfg -d on my pc and since then I can’t access my files in windows explorer.
WDMyCloud shows up as a networked pc, but whem I click on it I get an error message saying that I cannot access \wdmycloud from windows.
I tried another pc on the same lan and it connects without any problem.
Can someone help?
