Hello Kertész, We have just removed the version.xml file from the website to prevent the automatic update of The Bat! versions prior to 4.1.
The Bat! v4.1.9 that we have put to the website on January 6th resolves the index issue, so the users are free to move back and forth without any loss of data. In a next version of The Bat!, we will put a warning that a backup is in new format and is incompatible with previous format. We will also try to improve the MSI install script to check whether the key is OK for The Bat! 4.1. We will also modify the download page on the website to make the user explicitly agree with the update policy. -- Best regards, Maxim Masiutin Ritlabs SRL http://www.ritlabs.com/ ________________________________________________________ Current beta is 4.1.9 | 'Using TBBETA' information: http://www.silverstones.com/thebat/TBUDLInfo.html
