LabView unable to open design : Can anyone help recover?

Question

Having made some minor changes to my design and saved. LabView now refuses to open the design, reporting Memory Full, Load error code 1 and Load error code %ld:%p. Given this has effectively destroyed my entire design, I am keen to find a way to recover something.
The design is not large enough to get even close to using the available memory. I've tried the obvious rebooting the PC, but beyond that, I can't think of much I can do as I can't even get into the VI. Does anyone know of any way to recover the design?

Answer 1

The cause could have been one of many things, but last things I did was edit a cluster of numeric indicators to change the units from 'C' to 'Cdeg' (mistakenly thought C was centrigrade). To do this I just changed the C to Cdeg on the unit after the numeric display. My design then uses a VI server ref and Value property note to write a value into the cluster element. I also changed the unit conversion in generating the number to write to Cdeg (so it matched what the element expected). After doing this, although the units matched, an error was reported. Instead of dragging the numeric out of the cluster and then putting it back to clear the false error (something I've found to work in the past). I thought I'd try saving and reopening to see if this would force the tools to revaluate the design and confirm there is no error (works on some other tools I use). My thinking was this would save having to regenerate assignments to the element, since these would be lost when removed from the cluster.
The design was hence reporting an error when saved (something I don't usually do, but I'd have thought not too uncommon). It was when I tried to re-open the design, that it failed to open.
My last back-up was 3 weeks ago, but I've managed to re-implement most of the changes (or at least those I can remember making).
