"Shipment for Virtual Products" and "k2mart"

[brontola85]

Hi,
I have purchased the plugin "Shipment for Virtual Products".
I use it with Joomla! 2.5.6 Stable and Virtuemart 2.0.10 and k2mart.
the download link is sent only if I disable the "k2mart" plugin.
K2mart is very important for me, it converts items k2 in products of the store..so I can not disable it.
can someone help me?

Sorry for my bad English
