Thanks, I ran into that I think, or it could be something else, it isn't working anymore.

I now use this, that should work for at least a while (if you have a better way I'd gladly hear so, but I think it is limited since you have only 10 digits and you want some accuracy on the milli or microsecond level, the best I can do probably is to add 110000000 to it):

$req['nonce'] = substr($mt[1],-7).substr($mt[0], 2, 3);

I get this error message back:

invalid nonce parameter; 0 8905540614

I don know why it gives a zero first, but the 8905540614 is the nonce I send. It's kinda weird, because it is 10 digits and it's ever-increasing (I reset the keys), so something else might still be causing it.
