bad linkage to sub vi

[ssnp]

I am using labview 11 and recently upgraded using service pack 1, some of sub vi i am getting error message bad linkage to sub vi although there seems no thing wrong. I could see the sub vi in project explorer.

Open the top level VI. Go to the error sub vi. It will probably be grayed out. Right click and select re-link.
