Hello, after having problems with my older mp4, the seller decided to give me a new one. So now I have this Blaze mp4 1.8" inch screen (firmware version: B809K8V2.0 2006/11/17 9.0.50 2006/10/30). The thing is I connected to the usb port and and my pc didn't recognize it, I try to connect it on the other port and finally did. I started to copy mp3 and amv files to it, but it seems when the file is bigger the player stucks and appears an error message: ... File cannot be found, verify acess route... or something like that.
Besides it has problems while playing amv files or some (not all of them) mp3 files.
What should I do? I hope you understand my (very bad) english.
