Make sure that you DO NOT select the "Install Sample Data" option or your data will not be converted.
If this does happen to you take the following steps to correct this problem.
- Drop to the MS-DOS prompt and change directory to the DATA folder directly under the POS Pizza folder.
- Delete all .PZ5 & .CLK files using DEL *.PZ5 and DEL *.CLK from the command prompt.
- Change directory back to the main POS Pizza folder and then run Dcvt4to5 /L. This will force the conversion utility to convert your 4.0 data to the new v5.0 format.
