I got the following error when I tried to do that

It's an older file. You'll have to use a hex approach. (or, again, send the file to me)

How would I find it in a hex editor?

Edit: I did some more poking around, and I'm pretty sure there's no version string.  See below.

Can you send me the .sb file? I'd like to debug that 

Here you go

I'm thinking that's a Scratch 1.2 file. Scratch 1.3 uses ScratchV02, so it must be earlier.

No, it's older. The latest it could be from is 2005.

I didn't say it wasn't older 

But yeah; I just checked using Kurt:
* the file I just saved with v1.2 has 'scratch-version': '1.2.1 (6-Dec-07)'.
* your file doesn't have a scratch-version at all.

EDIT: yup, file.sb's info table just contains:
{'thumbnail': <Image(file thumbnail)>}

Must be pre-1.2, then!

There is a problem here. I took a look into the file and discovered it used the "look like" block from 0.2, but the "broadcast" block from 1.0.

This is very interesting, perhaps from a development version, maybe 0.3?

Well, lookLike is the name of the blockspec of switch to costume in 1.0.
So we can't really know how old it is, except from October 2005 at the latest.

except...
It may be the same version of the project here. This is possible because they left the projects backward compatible by just changing the name of the block instead of the name of the blockspec. This would date it to sometime in 2004, as the version shown there is likely "0.2" (although they didn't really have version numbers back then).

You didn't tell me you found SBs!

I didn't??
They weren't really SBs, anyway, they were SCRATCHs!!!

Oh, you did mention that. Maybe it would work better with the original .SCRATCH?

It's the same file; I just renamed it to change the extension to try to work with Kurt.
