Export problems...

Export only works for some objects. It would work for a basic cube or anything else basic. If its something complex it will say “Python script error: check console”. i tried to install more versions of python. but it i still have the problem. Any ideas on what to do?

What version of blender are you using ?
What operating system are you using ?
What does the error message in your console say ?

i use blender 2.4, 2.5 and 2.57. (it does that for all)
Windows 7.
and the error message says “ValueError: chr() arg not in range(256)” I think it says that anyway. its the only thing that says error so i can only assume its that.
