Hi pweep and welcome to Mobile Read
I don't know if this will help but, it seems as though I have read about this same problem before and it involved the no-no of using Sony Connect and calibre on the same computer or something...
I don't have experience with calibre but saw this information at the below link.
Check out the wiki on calibre, the user manual, calibre F & Q, and of course mobilread calibre section for more information.
I hope this will help you.

"I used calibre to transfer some books to my reader, and now the SONY software hangs every time I connect the reader?¶
You should not use both calibre and Connect to transfer books to the reader. You can fix this problem by:
* Removing any storage cards from your reader.
* Deleting the file media.xml from the reader’s main memory using windows explorer (search for the file to find all locations where it is present). Note that by doing this you will lose all your collections, bookmarks, history etc.
* Unplugging the reader and waiting till the list of books shows up again
* Re-connecting the reader and starting the SONY software"
