As of April 23rd I have suddenly ran into problems with my data feed.
On April 22nd my feed worked as usual... inserting all products.
Starting with the April 23rd upload google processes the feed on 800+ products as '0 of 1 items inserted'.
I added no new products between this time... so this leads me to believe that google made changes to the way it reads the feeds.
Has anyone else ran into this issue?
Any resolution?

I get this message from google...
Our system encountered an error when processing your data feed.

Line 15 looks like this...

"<link>http://www.experimedia.net/index.php?main_page=product_music_info&products_id=706</link>"

Like I said no problems on the 22nd then suddenly having issues on the 23rd when there were no changes to my system, feed, or new products.
