Assembly version problem

Hey guys,

I just stumbled onto a problem: I get 5 (the same) errors about the assembly version of the project which I am working on. I'm an intern at the company where I currently work for, and a few previous interns worked on the same project. As it wasn't finished, they asked me to continue with it. I had a look through the source code and I found these assembly errors. I'm not exactly sure what causes it and how to solve it. Here's the code of the assembly part:

Code:

//------------------------------------------------------------------------------
// 
//     This code was generated by a tool.
//     Runtime Version:2.0.50727.3603
//
//     Changes to this file may cause incorrect behavior and will be lost if
//     the code is regenerated.
// 
//------------------------------------------------------------------------------

using System;
using System.Reflection;
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;

[assembly: AssemblyTitle("OneStep Printer Application")]
[assembly: AssemblyCompany("DHL")]
[assembly: AssemblyProduct("OneStep Printer Software")]
[assembly: AssemblyCopyright("Copyright © 2009")]
[assembly: ComVisible(false)]
[B][assembly: AssemblyVersion("0.1.0.-1")][/B]
[assembly: AssemblyFileVersion("0.1.0.-1")] 

I hope this piece of code has helped a bit. The error is on the AssemblyVersion line, as I highlighted in the code. This is the exact error:

Code:

Error        3        Error emitting 'System.Reflection.AssemblyVersionAttribute' attribute -- 'The version specified '0.1.0.-1' is invalid' 

If I wasn't clear about something or you need some more information about this, please tell me.

Thanks in advance.

Kind regards,
