To all users, who experience flash error #2038 on Mac based browsers (Firefox, Safari), we have released fix 3 for FileVista v4.1 which solves this problem. This release also includes some other fixes especially for Mac platform.
Note that #2038 is a generic error and it may happen on other cases such as using self-signed certificates with SSL (most of these causes are flash plugin bugs which we can not fix).
This fix is especially for Mac platform problems, it should also solve Linux based problems but we haven't tested it yet.
Please see this topic for more information and download link for the fix:
