Load errror code 11: VI version 6.1 cannot be converted to 7.1

[sam1]

I have  several vi's that were working with labview 6.1/7.0.  Now I have installed 7.1 and does not run the program showing the error; "An error occured.......   load error code 11: VI version (6.1) can not be converted to the current version labview (7.1) because it has no block diagram."

what should i do to make it run?

Thanks for your help.

If you have saved a VI without a block diagram, you cannot load it in any version of LabVIEW other than the version you used to remove its diagram.  You will need to find the original source VIs (that still have their diagrams) and load them in LabVIEW 7.1.

P.S. - Unless you have a really good reason, you should not save VIs without their block diagrams.
