Video: "LiteSpeed was unable to retrieve license information. Restores can still be performed" (4334056)

All Backups fail with the error: "The backup has failed because LiteSpeed was unable to retrieve license information. Restores can still be performed"

The LiteSpeed console shows the correct information , the license key is correct and all the permissions are ok.

There are more than one production key in the ProductLicenses.xml (located in C:\Documents and Settings\All Users\Application Data\Quest Software) file and Litespeed fails to work when this happens.

The ProductLicenses.xml file looks like the one below:

<?xml version="1.0" encoding="UTF-8" ?>
<LicenseFile>
 <Licenses>
  <License ProductName="LiteSpeed for SQL Server" ProductVersion="6.5.2" KeySaveDate="40969.6804196065">
   <LicenseKey>one old key here</LicenseKey>
   <SiteMessage>site message here</SiteMessage>
  </License>
  <License ProductName="LiteSpeed for SQL Server" ProductVersion="7.1.0" KeySaveDate="41418.7272791088">
   <LicenseKey>another key here</LicenseKey>
   <SiteMessage>site mesage here</SiteMessage>
  </License>
 </Licenses>
</LicenseFile>

WORKAROUND

Please remove the older key and leave only the newer one.
For instance the example above should be replaced by: 

 <?xml version="1.0" encoding="UTF-8" ?>
  <LicenseFile>
   <Licenses>
    <License ProductName="LiteSpeed for SQL Server" ProductVersion="7.1.0" KeySaveDate="41418.7272791088">
    <LicenseKey>another key here</LicenseKey>
    <SiteMessage>site mesage here</SiteMessage>
    </License>
   </Licenses>
  </LicenseFile>

STATUS

Waiting for fix in a future release of NetVault LiteSpeed for SQL Server
