Hi Svend,   
  
 Could you provide us with the assertion failure message, as well as which version major version of FinalBuilder you’re using (i.e. 5, 6). You should be able to open a project without a log file without getting an assertion failure.   
  
 Regards,   
 Paul.

Hi Svend   
  
 I just had at look at this assertion, it is raised because the log version table is empty, which should never happen unless the log file is corrupted. Try renaming the project’s log file, FinalBuilder will then create a new log file. If you want you can send us the old log file (contact support first to check the size limits) and we can try to repair the file(can’t promise anything though).
