One of the 3 things is null. GC, MyChar or Inventory. If I had to take a guess, I'd say MyChar. Why it's null though, I can't offer and support.

Make sure the character is not null. add the line

Code:

if (GC.MyChar != null)
{
[COLOR="Lime"]//the foreach code.[/COLOR]
}

Learn how to debug your code using breakpoints.

if(GC.MyChar.Inventory.Count > 0)
{
....
}

Go to telport.cs and remove these lines

Quote:

foreach (Game.Item I in GC.MyChar.Inventory)//error line
{
if (I != null)
{
GC.AddSend(Packets.AddItem(I, 0));
}
}

you dont need it any more cus you are not updating/converting you are just copy pasting the load/save/sql commands
but trust me thats not gonna work delete the whole source and start learning/building your own Pserver
Ps.Dont waste your time with those sources and start learning how to do your own shit :xD

As already stated, something is null.

Your character, your inventory or the client itself (which should never happen as it would need to NOT be null for this to trigger).

Place a breakpoint on this line and when it hits it you will be able to see what the value/structure for all these things are. Find the one that is null and there's your problem. Then backtrack it to ensure this doesn't happen again.
