Scene DUF file corrupted on DAZ Crash (or maybe it didn't save correctly before the crash?)

DAZ Studio Public Beta crashed during a render with Failed to Allocate Memory and now having restarted DAZ Studio Public Beta and trying to open the DUF Scene file that I was rendering I get this error:

2016-11-11 16:21:45.257  Json Parser (824862,39): Syntax Error - expected ',' or '}'
2016-11-11 16:21:45.274 Error reading file, see log for more details.

I doubt that the crash corrupted this file so I think it must of been saved incorrectly but unfortunately I did not try to re-open the saved scene before I started rendering.

Hints to the fix? I will look now though with a text editor at the scene DUF file.

OK, 7 Zip says it's a data error in the compressed file and the scene file once extracted and looked at in an text editor is truncated.

This was after I made an instance node of 7 lawn grass models and then duplicated and positioned those duplicates 33 times in DAZ Studio Public Beta.

Please send Daz the scene file (with a note of the content used). This happens rarely, but I have seen a few instances - it looks as if there's a glitch while compressing the file, so the latter part of it can't be uncompressed. The atual files I have seen had the break in the middle of a block of data for a plug-in (but not the same plug-in), I don't know if that's significant or just rflects the fact that that was the biggest chunk of data and therefore more likely to be hit by the random issue.

Sorry, I already overwrote it. I will construct the scene again though and once I add the instances it will probably happen again.

Found this thread.

I have several files like that after a laptop crash.   IS there a way to fix those?   and I don't know what I all used in those scenes..

If they were OK before and are bad now that sounds as if the drive went bad and corrupted them. There are tools for repairing zips and other archives, but I've no idea how well (if at all) they would work. Unfortunately if it is disc corruption then you may have more than a single bad/missing byte so you could find even the best repair tool will fail.
