can not upload from itunes10 Windows to ipod shuffle - error 50

I have an ipod shuffle 4th generation and am using itunes10 running on a PC Windows XP SP3.

When synchronising the device from itunes, I always get the message <itunes is unable to copy "song" to ipod "name" because of an unknown error (-50). Irrespective of doing this with a complete library or synchronising just 1 song, always same error. I have now deleted all content from the ipod shuffle, and tried it again. Same error.

I know an ipod reset tool is available on the site, but it is currently not accessible. Anyway, resetting the device everytime when the library does not synchronise is definitely not the right solution.
