I need assistance from expert .NET programmer!

[Vercas]

Hello!

I am working on a project, vHub, an all-in-one tool that does many things, including but not limited to:

• Converting models
• Extracting mipmaps from BLP's
• Edit MPQ archives

Now, I've fixed all the bugs except these:

• When the Model Converter form is created, the only tester I've sent the program to gets an exception about an icon.
  I did not get this error. Moreover, the BLPer form is just the Model Converter form copied! And he doesn't get that error on the BLPer form!
• vHub takes command line arguments and uses them well. It seems to have a problem when opening an MPQ archive from command line arguments and if vHub just opened. The exception is thrown from MpqLib..ctor (Notice the double dots!) to MpqLib.open to my functions stack!
  But it has no trouble opening the archive later!

The bugs I listed are incredible. I cannot find an explanation for this! I cannot find anything that could bug either!

I should also mention that the first bug only happened to the tester, running Windows XP. I am running Windows 7.
The second bug happened to both of us.

I need to test the first bug a little more and I am not sure about the second...

I really need help, please!
