It is a courtesy to post your working code, when someone has helped you, so other can make use of it in future.
Thanks a lot. The system finally works now :)
The problem with the Part error is because for those ICs, the orbit goes off to infinity and does not return. The {} is returned from Reap[...] because no points were Sow-ed (or sown in the English Language as opposed to the Wolfram Language :).
Part
{}
Reap[...]
Sow
Thank you, the number of problems did significantly reduce ^^
Althought one is remaining... Part::partw: Part 1 of {} does not exist.
