When I run Daggerfall,I get an error called Error 0.I try to run Daggerfall again I get another error called Critical Error.I did what it said,but I get Error 0 again and when I run it again I get Critical Error and so on.

Did I do something wrong?

Never personally tried Daggerfall myself, but I have experiance with older games such as KOTOR 1... Daggerfall is like 10 years older but you could google those and find if it's an update problem or anything like that.
