The problem is that something in the "tables.vi" function is broken. Fix that problem and the build should work.
When you open tables.vi in the development system, does it show a broken arrow? If not, does the VI call any DLLs? Sometimes the app builder misses DLLs that it needs to include.
If you still are getting the error, post the tables.vi in 6.0 format and I'll look at it.
