error with my first grf need help!

[RSpeed tycoonfreak]

I just made my first grf.
It has to to replace the modern stadium.
But in the game I get this:

I really need help this time!
I used the nfo from the Multi story car park
And i only decoded mscp.grf
changed the sprites
and encoded mscp.grf

I think you broke something.

But all my crystal ball is telling me is that you broke the grf file.

Is this GRF for your personal use or release? cause I'm pretty sure it's a nono to use someone elses NFO.

Here we go again...
Stop using other people's stuff (Graphics, NFOs, Website content...) without asking them first! PM them, and they can decide whether you can use their stuff.

It's starting to get annoying.

EDIT:

remember, you can never ask permission too much.
