You can download the beta version of the program from
www.ezisolution.com/Downloads/rm18073/rm_1_80.exe
The way to upgrade is as follows:
1 - Close all instances of the program
2 - Make a full folder backup (this is just in case something going wrong)
3 - download the setup program
4 - Run the setup program
5 - Once done, start one instance of the program and wait for it to update the files.
6 - DO NOT RESTORE the old data, the new setup will keep all the data in there
You may like to reindex the files and check if all is OK, you can now start using the new version.
This upgrade will fix the problem with your barcodes.
