"cannot create session Bad address" seems to be the common error message
from programs run under the examples directory.
Attached file with output from several example programs; first output
from examples_v2 dir and then same command from examples dir.
Hope this helps, and let me know if you need any more data - not a
problem.

Raul,
Can you copy some of the output of the errors you get running programs
in the examples directory as well as any other problematic programs? Any
details would be appreciated.
