Can´t attach anything to pod - because of mechjeb?

[Vasa]

Hi!

Only been playing KSP for a few days and no problems from start. Now a day ago I wanted to try mechjeb addon (to hard for me without I guess). The problem is that when I installed mechjeb in gamedata folder, I cant attach anything to a simple pod! No engine, no fueltank or anything at all! No problems to attach on the top of the pod or the side but impossible to do under....! If I load an old rocket from my savings I can dettacht and attach the pod without problem but not with a new rocket!

 

I have tried to remove mechjeb - same problem!

I have tride to uninstall and install the game again - same problem!

 

Any idea what might be wrong?

 

Sry for my bad english!
