My game crashes after a specific location with this error:

Can somebody help me fix this?

Always post the logfile.

Looks like a bad world file.
Have you spoken to the author?

[Minecarft]

No, I just downloaded this and this error only occurs in activity mode otherwise in explore mode it is fine.

Every activity or just specific activities? Share the route and activity names.

I only played two activities and both faced it

There are a lot of missing .sms, .wav .ace and .s files. I cannot say where the crash is coming from. But I would at least try to fix the following errors by getting the missing material or linking to existing files.

This seems like a world-file (ie. route) issue, possibly a location not having a name. The code that causes the exception:

    foreach (var platform in worldFile.platforms)
    {
        if (State == DisplayState.Auto && Platforms != null && (!Platforms.ContainsKey(platform.ItemName) || !Platforms[platform.ItemName]))
            continue;

The exception could be caused by platform.ItemName being NULL.

so what should I do?

[derekmorton]

As said before

Looks like a bad world file.
Have you spoken to the author?

[Minecarft]

no

He is the only one who can fix it.
