Unable to place items in own server

[Limuz]

Hi there!

I got a problem with my Tekkit Lite server. I recently started it up, and I am perfectly able to place Vanilla blocks, like bricks. I can see items like a bucket of oil, basalt, mass fabricator, pipes etc. in inventory selector in creative mode, I can place them in my inventory but I am not able to place them. They just disappear from my inventory! Can you guys help me out?

Are you too close to the spawn?

Got it fixed, turned out that I was launching my server with minecraft.jar instead of tekkitlite.jar -.-
