i made some recordings using my sony mz-nh700 md. i transfered the recording files-suffixed .oma- to my drive d after i recorded them. my system was installed in drive c. so was the sonicstage software. but recently my system crashed and i did a system recovery, which erased everything stored in drive c. now i couldn't play my recording files in sonycstage or upload them to my md any more. the sonicstage always tries to download licenses from the internet but always failed. i guess the system recovery must have erased my licenses to the recordings. do i have any chance to play my recordings again? they are very important to me! any help or suggestions will be greatly appreciated! thanks!
