Problem - Index out of range

patrique2001 · Jun 12, 2021

Hi,
I've got a problem with my BTB project. Last night I saved my progress after some work, as usual. Today, when I was trying to load the project, I've got an error "index out of range". I didn't change anything in XPacks, and also I don't have any backup...
Here's the full message - it's in Polish language, but I saw similar thread with Spanish error message, so...

************** Debugowanie w trybie JIT **************
Aby włączyć debugowanie w trybie JIT (just-in-time), plik .config tej
aplikacji lub komputera (machine.config) musi mieć
wartość jitDebugging ustawioną w sekcji system.windows.forms.
Aplikacja musi być również skompilowana z włączonym
debugowaniem.

Na przykład:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

Gdy debugowanie JIT jest włączone, wszystkie nieobsługiwane wyjątki
są wysyłane do debugera JIT zarejestrowanego na komputerze
i nie są obsługiwane w tym oknie dialogowym.

All we can see from that error is that something went wrong with a string object.
(BobsBits.SObject...)

BTB makes backups of your venue file. You will need to open the temp folder (this location can be seen by going to the View menu, then Options > Temp Files)
The files in that location will have randomized filenames (8 characters with a 3 character extension).
Copy the most recently modified file and rename it to venue.bin and put it in your project folder (but keep hold of the previous venue.bin in case this doesn't work and someone else suggests something).

Important safety tip: ALWAYS HAVE A BACK UP OF YOUR TRACK! AND SAVE REGULARLY!

I usually have four saves of a track at any one time, and I just save over the earliest one at least every time I work on the track.
