I am trying to record a macro, that includes 120 clicks (filling a farm in a game

When I click stop, I see the recorded contents in a fresh window, the macro content seems fine.
When I am trying to save, nothing gets saved.
It doesn't matter what storage I choose.
When I click Files, I get a red text (indicating an error, I presume) "Error occurred while building file tree: Error: Error calling method on NPObject."
When I click Bookmarks, I get a list of files that I can find in the indicated directory in Preferences. The filename, that I used to save the macro exists, sometimes with extension .iim (shown in the macros window), sometimes without the extension (only shown in the macros window, cannot be found in the directory). But when I click "edit", It always is empty.
When I click play, it doesn't do anything (probablu because it is empty).
I am using iMacros for chrome 3.5.3.
Chrome 14.0.825.0 dev
Mac OSX 10.6.8
(The installation of iMacros for chrome did not include any demo macros.)
My preferences are set like this:
Macros directory path (I created this folder manually, and it contains the macro files mentioned above, with extension .iim): /Users/username/iMacros/Macros/
Logs directory path: /Users/username/iMacros
I have attached the log file, found in the iMacros folder.
I have also found a log file in the /Users/username/ folder. (but I have experimented with the previous beta as well, so I don't really know which version generated which file). I attached this one as well. (zipped both first, because .log is not allowed in your forum)
