One coworker of my company is having this problem with the Flash.
Everytime when he try to convert an objetct to a movie clip, the Flash crashes and the message above appears.
I've already reinstalled the Flash and I applied all the updates.
I've tried this solution too (http://www.ehow.com/how_5009906_fix-runtime-error-r.html), but no sucess.
Anybody have any other solution for this issue?
then try resetting preferences: http://forums.adobe.com/message/4348882
if that fails, uninstall, run the cleaner (http://www.adobe.com/support/contact/cscleanertool.html), restart the computer and then reinstall flash.
if that fails, the problem is some other program.
Well, I'll try this solution and keep you informed about the results.
And, I wonder if this problem could be related with the fonts?
In his system have at least 3k fonts installed. Could it be the problem? Or related to it?
