Regions.FindRegion makes Testcomplete to stop execution without any information why

Hi, I have developed an script extension to work with keyword tests. In that script I use the Regions.FindRegion method. Today, I don't know why, it 's failing all the time when I try to use it with a new Region.

Debugging the script testcomplete has crashed twice today. For some reason, when the execution gets to that line, the execution stops, and it does not show any information in the log.

I tried a try-catch but nothing, the executiong just stops, even if i disable the "Stop on Error" checkbox for the current project.

There could be a limit for the number of Regions stored in a current project? Any clue?

Thanks in advanced,

Gabriel.
