Adobe Acrobat editing

OK,
I recently created some pamphlets and invitations on Adobe Acrobat and want to make changes to these docs, but can't seem to do anything as I must have created them with some limited security or with security features on. I am not even sure if I am describing this correctly, but anytime a doc is in Adobe Acrobat form, is there any way for us to edit or change parts of the document before we print them out. I know docs that are available online from Legal or Educational agencies are not able to be edited as far as I know, but something that I have created myself, I am a little confused as to why I can't make changes or edit the files, as I do not want to have to start from scratch. Any help would be much appreciated. I have Adobe version 8 I believe.

So my only option really is to buy Adobe Professional? Are there any ways I can edit with just the free Adobe I downloaded? Thanks so much for your help!!!

 

Thanks so much again. The only thing I am confused about is if I open up a file with Adobe and it is only viewable in adobe, can i change it over to whatever free version or trial I test out. I had another idea but I am not sure if this will work either. What if I take the items I want to edit and scan them with a brand new scanner and try to edit the docs or files that way. Is that a possiblity I may have to make this work? Thanks alot.

 

Which Adobe product did you use to create the documents?
Was it a "Trial / demo" version?

Although I've never used it, Adobe does offer a 30-day trial of their PDF Editing software. If that is not the product you've already used, maybe it would work as a temporary way to get your documents fixed.

I use free OpenOffice (I use the Writer module for Word-type docs) to create pdf documents. It does an excellent job of converting to pdf. It has always preserved all my text formatting and images, and even keeps Live URLS! Live URLS is something that even some of the more expensive shareware pdf-creators cannot accomplish.
(if you'd like to try OpenOffice, I highly recommend the thinstalled version available on Thinstall.com demo's page, it is 115 mb, totally self-contained, and can even be run from a flash drive.)

You could try the scanner route, but using OCR (optical character recognition) software to recognize "text-as-picture" is probably never going to be 100% accurate, you might end up doing a LOT of manual spot-fixing.
If it was me, I would probably rather copy & paste from the pdf docs into OpenOffice, edit there, and export all over again.

Edit Added --
There are a lot of free "Pdf Converters" out there, such as CutePdf, they work by installing as a printer driver on your system, and then in your regular word processor or spreadsheet app (any app that can print), you choose to print to that "Pdf Printer", and the driver creates your document in pdf format.
There are also a lot of free pdf readers, like Foxit, Sumatra, and PdfX-change, which are much smaller and faster than the Adobe reader.
