Vvvvv not saving, creating temp files

HI All

I am having a problem that have appeared suddenly while cleaning up a complex patch with quite some sub patches.

I can not drag drop new subpatches into the main patch when they have subpatches in the subpatches. I can however create an empty patch in place and then rename the subpatch I want to the name of the empty subpatch and then it will most of the time load the subpatches.

temp files are created when I make edits with the correct patches inside, but on opening of the main patch subpatches are often not loaded.

Anyone have any ideas why this is happening and what to do about it.

Errors from tty below:

when saving a file and it does not work:

00:00:15 ERR : could not delete previous backup-file: C:\documents\Dropbox\_vvvv_patches\_natmus_elipser\System\ElipseVVVV\SubPatches\AltContent~.xml

when loading a sub patch that will not work:

00:00:18  *  : didn't create node; [C:\documents\Dropbox\_vvvv_patches\_natmus_elipser\System\ElipseVVVV\GeneralMain01.v4p, without name (ID: 206)](C:\documents\Dropbox\_vvvv_patches\_natmus_elipser\System\ElipseVVVV\GeneralMain01.v4p, without name (ID: 206)): Cannot open file "C:\documents\Dropbox\_vvvv_patches\_natmus_elipser\System\ElipseVVVV\SubPatches\AutoGain.v4p". The process cannot access the file because it is being used by another process
00:00:18  -  : To help us track this error down, enable the ExceptionDialog by either pressing CTRL + F10 or starting vvvv with /showexceptions.

The part of the file being used by another process I don’t understand, I am not using the patch anywhere else and just running that one instance of vvvv.
