Hi,
I just installed crystalspace from ubuntu binaries (don't have enough time to compile it

). Somehow, whenever i try to launch any thing cs-related i get error message like this
stovo@pc1:~$ walktest /opt/PlaneShift/art/world/gh_law.zip

I am pretty new in linux, so I don't know what to do now. Please, can anyone help me?
