If you had registered DT Pro Office during the public beta period, it should have remembered your registration; it did so for my copy.
Check your license code email to make certain that your registration is for DT Pro Office (not DT Pro, which has a different license code).
If you have the license code email for DT Pro Office 2.0, enter the information components (Name, Organization (if any), License Code) into the corresponding fields of the registration panel (Help > Enter License).
After entering the last field, press the Tab key. The Register button should activate so that you can click on it to finish.
I ran into the same problem, DTPO 2.0 is locking me out of the OCR module because it believes to be in demo mode. (I just emailed support@devontechnolgies.com about the problem).
I tried to reenter my registration info, but although it shows up, for example in the splash screen, it didn’t help.
Strange. I just updated DTPO 2.0 today, then OCRd a 28-page document plus several smaller ones.
Try clicking on the application name in the menu bar, then choose ‘Empty Cache’. Quit the application and relaunch it.
If that doesn’t work, perhaps your registration .plist file is damaged. You can find it at ~/Library/Preferences/. Delete the file named “com.devon-technologies.thinkpro2.registration.plist” and then reenter the information from your license code email at Help > Enter License. Press the Tab key after entering the last field of that information EXACTLY into the registration panel. The Register button should then activate so that you can click on it to finish.
Both “Empty Cache” and deleting com.devon-technologies.thinkpro2.registration.plist and reentering registration info, didn’t solve my problem. Please help!
I’d like to add that on my system Mail import is affected, too. I just tried to import a mailbox and it stopped after 200 messages complaining that I use a demo license (which I do not!) - so not only OCR is messed up.
