Data Feed for Wholesale Central on oscMax catalog

I need a product datafeed pulled from the mysql database for my oscMax 2.0 RC3 store to submit to my Wholesale Central account once a week. The script doesn't actually have to sumbit the datafeed, I can do that manually, but it needs to generate it in a text file that I can download and re-upload to my Wholesale Central account when new products are added. I previously hired someone else to set this up and I believe they modified a contrib for Froogle Data Feeder 1.62 (This feeder has been revised to work with Ultimate SEO URLs 2.1d - [login to view URL],2823 - but it looks like they have SEO urls set to false) and renamed it feed_wc.php. This worked for the first few months, but recently it stopped working. Now it just generates the column titles, but does not generate the actual products or any of their information. After this was originally installed, I installed another contrib to force the customer to buy a minimum amount before they can check out, and may have inadvertently messed it up somehow. I'm not sure exactly when it quit working because I haven't tried to generate a feed in the last month. I know it was working before that. I need someone to track down the problem and fix it. This site is heavily modded. Instructions for the Wholesale Central Data Feed: Your data feed must be a tab-delimited text file.
