OCR stopped working yesterday

I was using Devonthink yesterday and was able to convert “PDF document” to “PDF+Text” with the OCR menu. Then it stopped working and I cannot convert any documents anymore (even ones I converted yesterday). Is there a problem somewhere? Perhaps with the Abbyy service?

Have you rebooted?

I hadn’t but now have and it makes no difference.

What is reported in Window > Log?

Thanks. It says Analyze Pages Error, licence pages remaining 0. Maybe I have been OCRing too many pages of late. I didn’t realise there was a limit.

See Is there a limit on OCR in Devonthink Pro?

Thanks very much Christian that advice fixed the problem.
