Check with the service provider of that particular account. It appears to be an error code that is specific to something about their business, not a general Windows error.
All of a sudden I'm getting an error (ErrorID: SL010) every time I try to access one of my online accounts. I can sign on but when I click "View My Account", I get the error and I can go no further. It happens with both IE and Firefox. Can anyone tell me what that's all about? Thanks.
