fallo al subir audio

[Soloks]

Hola! Acabo de probar con un archivo llamado agua.mp3 y me ha dejado (lo he hecho desde tu cuenta). Puede ser que sea por el tamaño del archivo. Cuanto ocupa?

3,30mb pero vamos que eso diria que no es por que tengo subidos mas pesados, siendo el que mas es de 13,5mb.

Tengo que subir dos nuevas en una me pone que se ha subido correctamente pero cuando voy a buscarla para ponerla en la pagina simplemente no esta, en la otra me saca este mensaje de bug
