Format : error opening file.

Answer 1

It appears that Wireshark does not currently support the K18 file format; K12 and K15 are listed as supported, but not K18. Also see this question and answer.

Answer 2

Try one of the automated builds with a version number of "SVN-53452" or later; somebody finally filed a bug for a failure to read a k18 capture, and attached a capture file that showed the problem, so it was finally possible for some reverse-engineering to be done to handle that file, at least.

If that still doesn't handle it, file another bug, and attach the capture file, so that more reverse-engineering can be done.
