Can't find VirtueMart among Components

[mausci1969]

Hello everyone,
I'm experiencing a weird phenomenon after having correctly installed VirtueMart (I've tried different versions: 2.08, 2.6, 2.66) in my Joomla 2.5 environment. Even though the installation is successful, and I can visit the Shop link, I don't see it among the Components Menu (and so I can't reach it anymore). Has anyone ever seen something like it?
Thanks in advance.

Usually an issue with Xmap. See http://forum.virtuemart.net/index.php?topic=116292.0
