Odd behaviour with fpga code...f

[matrix]

Hi there!

I got some fpga code to work and then i call it from a labview vi. All of a sudden, i end up with an error when i try to run my vi that uses the fpga code. I looked at the fpga code and it shows the run arrow as greyed out to indicate an error. I will post the error and block diagram below... I hope someone will be able to advise me on how to correct it.

I could solve the problem by rewriting the piece of code from scratch which i already had done before, but it takes time and it seems it might happen again sometime in the future, who knows!

Thanks.

If you would post the code and the error message it would be helpful.  I'm not sure what you mean when you say that the run arrow is "grayed out."  A vi with an error should have a run arrow that's broken.
