Probably the best thing for you do would be copy and paste the code for IG88's ship here. (Remember to put it inside Spoiler tags)
Sometimes it just takes a fresh set of eyes to find the error.
When you copy and paste and something doesn't work, its usually down to missing one < or > somewhere.
Just out of curiosty, what are you using to edit the XML files?
If you are just using the Notepad that comes with Windows, might I recommend you take a look at Notepad++
It has built in syntax highlighting, which makes it much easier to spot any issues.
There are also a range of XML plug-ins for it, to make error spotting even easier.
Hope we can be of some help to you,
