If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.

Thanks

You can check the similar threads at the bottom of this post but most are IPN issues and I believe if you search the forum for "1054 Unknown" you might have better luck

Looks like somebody did an Upgrade and didn't Upgrade their database all the way ...

Should see several threads on a search, as kobra suggested, or peek at the bottom of the page and see if any of the similar threads help ...
