Uninstall Logbook Pro (Start...Control Panel...Add/Remove Programs).
Search for the file 'DCube.OCX' and delete all instances found.
Reinstall Logbook Pro and reattempt. If it fails again, create a backup of your data, e-mail the .BAK file to firstname.lastname@example.org and advise the exact date range you are entering to show your data and we'll try to duplicate the issue. Please do this ASAP as we are planning an update out within the next week to add a few features and correct a few other reported issues.
Repair didn't work. It appears there is a discrepancy in the data. The total time for SE and ME does not agree with the report's Grand Totals. To be specific, the SE time is off by .3 hours from the program's calculated Grand Totals. If I run enough reports while changing the report dates, I can probably narrow down to the day where the data got corrupt, but that is going to take forever.
