Problem Uploading Mp4

[TONYBERNARD]

Purchased Karoake songs from a website, downloaded in MP4 format, uploaded into Hoster and they worked fine. My computer crashed 2 days ago had to redownload Hoster, everything is fine except the Purchased MP4's are showing extended time. For example: 1 song is 3min long but when added to playlists it shows as 11 min. I have redownloaded songs, tried several different ways to download them and it continues with extended time. Again, they worked for months and only since the redownloading of Hoster I am having this problem. Using 5.06 version and Windows 7 64bit. I originally tried 5.08 had too many problems and had to revert back to 5.06. Please help and advise...Thank you Tony
