Jeez, where do i begin. U-232 v4 uses class.bencdec.php, so takeupload, download and use that class. You come along and post some benc.php probably lifted out of TBdev 09 that is not compatible in any way, it will cause untold errors.
If you don't know nothing about U-232 structure then please refrain from posting garbage here napon, I'm more than capable of answering any support myself. For the record that bad bencoded data error is a client issue not a code issue therefore not my concern. Whats even more laughable is that a member kira says thanks it works
. Trust me if your runningU-232 v4 as you have said, that code posted is useless, I don't replace stock default bencdec with much better code for the hell of it.
