In the future should I avoid running Polish books on EPUBs that have been converted from Amazon purchases or does it not matter and I can jump through the extra hoops by doing the conversion?
Sorry, I don't know. My memory, says the error is related to an internal font. They can be obfuscated and the key is in the file. But, I would have thought the initial conversion would have handled this. Or that Polish would, but might be depended on the options. But, if it needs another conversion step, you might need to accept that it is needed.

Edit: I think I may be confused; I may not have previously uploaded these converted books with the Extended Driver. So maybe the error wasn't due to Polish books?
Again, I don't know. You probably need to experiment and check.
