Hi, I wrote a book and in order to submit it, it needs to be in Adobe format. I tired my little 6.0 reader, but I can't create a new file. I guess I have to buy the Adobe program. At costco, there is a 6.0 upgrade for $89, and on Adobe's website, they sell the standard edition for $299! I only need to put my book into adobe to send it off. Do I really need to spend $300? Will the $89 upgrade work? Is there a place to try it free for a week? Or are there any stores that will let me pay to convert? I really need to get me book out! Thanks.
