FPGA compilation error 1000

[Harlequinade]

Today when I wanted to compile my VI, I got this error and don't know what the reason is and how to solve it. Next, I couldn't find anywhere on the forum / Google a similar case. 

Does someone has an idea where it might come from and how to solve it?

An internal software error has occurred. Please contact National Instruments technical support at ni.com/support with the following information:

Error 1000 occurred at an unidentified location

Possible reason(s):

LabVIEW: The VI is not in a state compatible with this operation.

Method Name: <b>Generate VHDL</b>

Hi Harlequinade.

Can you give me some information.

Wich LV version, OS and wich hadware do you use.

One what you can try: "Before compiling to a bitfile click the combination Ctrl+Shift+Run Arrow in the VI"

I use LV 2010 SP1 32-bit, W7 64-bit, NI PCI-7813R, however, I noticed the problem also on a W XP 32-bit installation. Both use Xilinx Tools 10.1.

When pressing the Ctrl+Shift+Run Arrow it indeed compiles and doesn't show the error. It asked me to save a number of subVIs which are used in the main FPGA VI.
