IT WORKS! :D
Thank you so much! ;)
And now I'll see about getting some sleep :)
(You're the best!) :)
You will have to be more specific as to what you are trying to do. Explain what it is doing when you try to export it. etc.
Fixed it, phew. Just had to make my world smaller like you said and it worked, I think it was because the heap space error thingy that it just went grey and it refused to show any info so I made my world into a 7x7 instead of 20x10 and then it worked. Thanks for saying that when you tried it out, else I wouldn't have known :)
