Apparently, this might happen when the folder which is opened as soon as you click the browser button, contains a virus or a file encoded with a codec which is out-of-date or not installed on your PC. After fresh program installtion, the folder which is opened when you click Browse changes for the default one, therefore the problem does not occur.
What you can therefore try, is running a virus scanner or updating codecs.
Best regards
