Google Base ~ No items inserted OC 1.5.4.1

Good Evening,

We have just done a fresh install of OC 1.5.4.1, and have uploaded over 3,000 products using Total Import Pro. For some reason when uploading to Google Base it says "no items inserted". We have been using T.I.P since August with no problems with Google Base.

If you put the google base url into a browser it only reports 1000 products. Any suggestions as we are stumped!

Kind regards

Eddie & Joanne
