Jean-Claude,
Sorry for this, but currently the latest version is not yet available for download. You can only the update feature to get it. The message "... try later" means that you tried to check for an update too often. You'll have to wait for a minute until you can call this feature again.
My previous answer was according to this.
It'll take a few days until I compile an installer with the latest version because I'm pretty sick right now.
HTH and the update feature is working now. If not, please let me know here.
Regards
Thomas
