I have 1,227 products currently...
1) When I create a Yahoo feed it works fine
2) When I try to create a Shopping.com and Google Base feed it will show the "Processing" wheel and then return me to the Admin Login screen.
I noticed it said "Error on page" in the lower left corner. I clicked on it and this is what is says

The only issue I've seen on here is Google Base with over 1,000 products. I have uploaded that .dll patch and I thought it uploaded successfully. I don't have to stop the server to upload that do I?
I think this is the last known issue for me right now

EDIT: In IE8 it redirects to the Admin Login screen and in Firefox it just hangs there spinning the Processing wheel.
These feed builders used to work when I was hosting with a different hosting company but I also had 300 products back then compared to 1,200 now. I am now hosting with Discountasp.net. If anyone is aware of any issues running AbleCommerce with them please post.
The only problem I have faced so far with them is in regards to Google Checkout. They had me go in and Disable Auth on the Checkout/Google folder in order to get it to communicate back and forth.
Thank you.
