OCR crash

[SAC13]

Hello, I have the need to make some long pdf files (e.g., >5,000 pages) searchable. I've just installed the trial program on my computer and my first attempt to do so failed. It seemed that the program was working through the many pages but then crashed. I hate to say it but the only pdf editor that has been able to do what I need is Adobe Acrobat, but as we all know it's extremely expensive. It's time for me to make a "buy" or "not buy" decision re Nitro so any help anyone might offer will be greatly appreciated. Many thanks, SAC13
