OCR conversion limit reached - Get a pro licence key to remove this limit

Good evening,

I am getting the above error message when executing OCRExtractRelative. However I have already purchased a pro key and it is all set up correctly in OCR tab and connected to pro end point.

I did have the macros running successfully for a couple of hours and probably used OCR conversation no more than 15 times before this error.

If anyone has any insight I would appreciate it gladly!

Thanks
