Data From Newer Version

[DARRIN PASTOOR]

RECEIVED ERROR MESSAGE "MISSING FILE", RE-INSTALLED QUICKBOOKS PRO 5 THEN RECEIVED MESSAGE "DATA FROM NEWER VERSION" TRIED UPDATING TAX TABLES TO ESTABLISH VERSION AGE TO NO AVAIL
HELP!

you will need to go online and get ALL available QB updates, not just the one for payroll taxes.
What has happened here is that your original file went through some upgrades via maintenance releases - by reinstalling your original qb version you no longer have these updates.
