Hi, I have no errors in my program, or warnings, or anything, it runs great.

But I see in the immediate window when my program is running a lot of errors, and I am wondering what they mean?
Code:
A first chance exception of type 'System.ArgumentOutOfRangeException' occurred in System.dll
A first chance exception of type 'System.IO.DirectoryNotFoundException' occurred in mscorlib.dll
A first chance exception of type 'System.ArgumentOutOfRangeException' occurred in System.dll
A first chance exception of type 'System.ArgumentOutOfRangeException' occurred in System.dll
A first chance exception of type 'System.Security.Cryptography.CryptographicException' occurred in mscorlib.dll

A first chance exception of type 'System.Security.Cryptography.CryptographicException' occurred in mscorlib.dll
A first chance exception of type 'System.Security.Cryptography.CryptographicException' occurred in mscorlib.dll
What do they mean?

Thanks
