OCR and License

Hi all,
I have recently purchased Devonthink Pro Office and have tried to import previously scanned pdfs as image with optical character recognition. I get the following:
You have exceeded the demo limit on the import of OCR documents for today.

how do you get around this and do which product we now have to buy to get this resolved.

many thanks,
