Trackback in VB Blog 2.0 not working

Recently I upgraded my VB to 3.7.4. PL1 and VB Blog to 2.0. Let me start off by saying that the Linkback function to the forums is working fine. But although I've checked the trackback settings (Enable trackback server is on in Blog options) multiple times I think that the trackback function to my blog isn't working.

I've used one of my personal blogs to check if one of the following links gives me a trackback notification:

Cuil not that cool Google Killer - Successful Forums | Search Engine Forum Optimization (SEO) |
Cuil not that cool Google Killer - Successful Forums | Search Engine Forum Optimization (SEO) |

The blog gives me the message that:

Trackbacks
No other blogs currently reference this blog entry

Anyone know how to fix that?

vB Blog trackback option is a vBulletin function and you should request asistance from them. As if i am not mistaken the trackback system in vBulletin requires a valid link within the entry.
