I used the auto-renumber tool. All the files within mp3tag are number correctly. I save, exit and look within w7 and the numbers are different. I go back into the tool, they are ok. What am i doing wrong. noob. See screen shots. The 200k limit on files!

For some reason, Windows Explorer interprets track numbers with leading zeros as octal numbers instead of decimal numbers.

Kind regards
