The reason for the mistakes-I didn't fully read the instructions on the "Upload" page at the ML
Especially this section-
Keep in mind that Celestia is a multi-platform program. Other platforms (Linux/Unix) don't consider the file "abc.jpg" and "ABC.jpg" equal, so you should enter all filenames carefully with correct case. Make sure directories like "textures\medres" or "models" are written all lowercase. Keeping everything lowercase and without blank spaces is probably the easiest solution. This is particularly important when creating 3DS or CMOD files.
Of course I have a Windows machine, so never noticed that this is a problem. Now that John V. is a team member, he is testing addons on Linux type machines.
To sum it up and to help speed the process of your addon being approved, I highly suggest double checking everything- spelling, texture names with capital letters or spaces in them, missing textures, extra textures, ect.
The guys at the ML have enough work to do on checking addons without the silly mistakes I have made by not reading the instructions completly.
I hope this helps other creators with their addons.
