Solved the problem. You can close the thread. Thanks!

Please don't do this. it's highly anti-social. The FAQ Advice you are asked to read (every new message prompt repeats the advice) explains not to do it and why not.

16. Should I close, delete, or edit threads I start?

You cannot delete a thread you started. Please don't mangle your own posts starting a thread, even if you solved your problem yourself or realised that the question was silly. Explain the solution, even if it was trivial. Often someone else will have the same problem.

Just zapping contents treats the forum selfishly as no more than a way to get answers and not caring about anybody else finding this content useful. Please restore the original, if necessary as #3 in this thread.
