My [Nokia E71]t1 [music player]t2 is not [working]t4 properly even restored to factory [setting]t4. How can I fix this [problem]t4? After I install some added [features]t1 on my [Nokia E71]t1, it started not to [work]t1 properly. Having it restored to default factory [settings]t4, my [music player]t2 is not [working]t4 properly afterwards (was [working]t4 before restoring). Please help me resolve this issue, it would be highly appreciated Thanks!
