Truncated Data Error when loading saved waveforms

Question

After  I save a waveform using the "Write Waveforms to File" VI (e.g. I save it as wave.lvm), I have tried to load it using the "Read Waveform from File" VI. I always get an error about truncated or unflattened data (error 116). Any suggestions?

Hello boomchild06,
After having a detailed look around the various databases that we use,
I've found out that this is a known issue with LabVIEW 8.0.
A workaround has been proposed as the following:
1. Place the Read Waveform from File.vi on the block diagram and double-click it to open it.
2. Go to the block diagram and double-click on the Open Create Replace WDT DLog File.vi and view the block diagram.
3.
Navigate through the case structures until you see the Deny Access
function. I would suggest saving this VI as something different from
this point on, so that you do not change the VIs in the vi.lib folder.
4.
Once you have resaved it with a different name, and I would suggest in
a different location, follow the output of the error cluster to the
case structure that it is wired to. I would navigate to the False case,
and then right-click on the border to remove this case.
5. Once
that is done, you can remove the entire case structure. I might
recommend doing it this way to avoid a lot of painful rewiring.
6.
Once you have this removed you can remove any additional broken wires,
the unbundle function and the Equals Zero function. You can either
chose to remove the Deny Access function, to prevent error pop-ups.
Alternatively,
the fix has been implemented in the LabVIEW 8.0.1 update which is a
free patch that can be installed. If you want to go ahead and install
this, it can be downloaded from:

I hope this helps.
