The same problem here, even with version 1.2 and after applying your fix.
This is anoying.
Your vminvoice.php and currencydisplay.php classes are handled as abstract classes by joomla and this causes the error.

Please check this as soon as possible.

My Order ID is 13128 and I have definetly received only one download ID for the component.
I double checked - no download ID for the plugin...

Hello,
I renctly purchased the vm Invoice component but I can't find a link to the plugin anywhere.
When I enter my download ID, there is only the component listed.
Could you please direct me to a link, where to download the plugin?
Thanks
