Oh, great to hear this and this is one more time reminder to me to not only rely on my memory, but also to spend some time from time to time to go through TestComplete's documentation.

try-catch is absolutely different approach from retrying.

This was not an attempt to criticize but expression of people's personal understanding. Quite often this happens because people are not oracles and thus may understand some situation differently than its author. Especially when situation description lacks details and author does not say something like 'don't ask me why this is done like that'. Considering your further explanation of the situation and assuming that adequate logging that makes it crystal clear that the test failed because of environment instability and this environment instability is expected, then re-trying the test might be an acceptable approach.
On the contrary, re-trying approach is often used to try to get 'green' test result. And if test passes within several attempts then nobody cares to find the real reason of previous test failure(s). This is a risky approach and this was the main idea of our notes about re-trying approach.
(And note, that people first tried to answer your question and only then express their opinion, so personally I would hardly consider this a criticism...)
