aspx fix on MadGerbil(repost)

Hi We have a dating issue on our MadGerbil website.... The problem is when we attempt to bulk upload a CSV of new products via the ADMIN section the product release-date (eg 10-sep-11) .... changes to a US date format (eg: 9-10-11) when displaying the products in the shop. So product due for release on 10-sep-11 goes on the website as 9th October. Also a product due for release on 25-Sep-11 is rejected due to incorrect date format. Which means we can only list products that have release dates up to the 12th of each month. The whole website is aspx - If you think you can fix this bug, I can email you full access / logins / FTP Hope to hear from you very soon Thanks Vince
