This is minor but critical update for last night released versions. There was a problem with committing files to SVN prior to releasing both Lite and Pro version, and last changes with a include line to load the file with additional functions failed unnoticed.
In turn a wp_redirect_self() function was missing. In some cases it was OK, with function loaded with some other plugin, and in some after number of operations you could see empty screen because redirection failed. I am really sorry about this problem, I will try to be more careful with future releases.
