I have had the unlimited version installed and functioning for a while now. But yesterday, after updating our website with new pages, I tried to run the crawl function and got several errors and no results.
The error screen disappears extremely fast, but I was finally able to do quick screen capture with the error message. It is attached.
To the best of my knowledge no changes were done to the /generator/ directory where the program resides nor to the config setup and I even uploaded clean copies of all of the basic files in case one had become corrupted, but the error still occurs.
