No valid database connection error

[randoms]

I have tried to install VM2.0.2 (3b) or upgrade from WM1.1.9 to VM2.0.2 (3b)  The module VM - FEATURED PRODUCTS always displays the following error message

"No valid database connection You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ASC LIMIT 0, 2' at line 1 SQL=SELECT * FROM `jos_virtuemart_products_vi_vn` as l JOIN `jos_virtuemart_products` AS p using (`virtuemart_product_id`) ASC LIMIT 0, 2"

Could you tell me how to fix this error?

Many thanks,
