Does it help if you press and hold the Ctrl or the Alt key on startup? This should enable the profiler start with default settings.

For the first time ever, when trying to open Profiler this morning I got the following error message:

Division by Zero

I then had the options of: Repair database, open new db, open different db.
NONE of these options worked.

I've reinstalled the program and still get the same message.

Any ideas???

Once, I had this kind of problem, and nothing worked : restauration file, repair...

As I run dvdprofiler on two computers, I copied all files in dvdprofiler/databases/ from the one where it worked fine to the other, and everything became normal.

If you have a database that works, or if you can restore a backup file on another computer, you should try that.

Try performing a System Restore to a time when DVDP was working.

I've done a system restore, rebooted (more than once) and cleaned up some of my registry and temp files.

After doing so I had to re-enter my registration key; but I still got the same error.

Pantheon,

Maybe the layout file you use got corrupted.

You can see which one you are using in the registry: start regedit.exe and browse in the left tree to:
HKey_Current_User\Software\Invelos Software\DVD Profiler

Then in the right of the screen you will see a whole bunch of keys listed alphabetically.
Scroll down to LayoutFileName, and doubleclick on it.

The part after the last slash is the actual layout. Make sure to leave in the entire path, and just replace the filename with 1 of the Invelos Default Layouts listed here below:

Invelos Default.dpl
Invelos Default - Medium Resolution.dpl
Invelos Default - High Resolution.dpl

I did as described but there were no keys listed at all.

No LayoutFile Name present in regedit.

Also - I copied my db to a dvd and my sister was able to open it without any problems; so it must be a problem in Profiler itself.

I find it very strange that I'm unable to uninstall it too.

What about if I was to install the Beta over 3.5, would that correct it?

I managed to uninstall the program. I restarted. Then re-installed Profiler again and got the same 'Division by Zero' error message.

Try to uninstall again. Then as Katatonia suggested, clean the registry.

Select the following entry in the left of registry editor:
HKey_Current_User\Software\Invelos Software - make sure Invelos Software is highligted in blue. Right click on it, and select delete.

Now clean the remaing files. Go to C:\Program Files --> delete the DVD Profiler folder.
Now go to the My Documents folder, and rename the DVD Profiler  to DVDPOLD. Don't delete this one because we need your database later on.

Now, I forgot to ask which version of WIndows you are using. But if it's Vista, in stead of just double clicking on setup.exe to reinstall the soft, right click on it, and choose Runas Administrator.

Just see if that works, than later you can move your database back to right location.
