Peppy

hi i'm sorry, i'm new here, i just have a question , i bought my netmd recently, and i did a terribly stupid thing to do , a song was taking like really really long to transfer it got stuck like around 42% for like 15 mins so i just disconnected the cable and took off the battery , now i haven't been able to check out anything , i can listen to mds but i can't use my netmd to transfer soongs, in open mg, it is not even recognized, it says that no external device was found and in sonic stage it alwasy gets stuck around 50%. So is there any way to fix it like using another netmd to record my mds or do i have to buy another netmd with a new software or something?
