chunkload doesn't work in JD 0.6.193

I have a premium account from uploading.com, but I feel like a rip-off.

The chunkload in JDownloader 0.6.193 doesn't work for uploading.com. It doesn't split into different chunk and it's always 1/1 only. If I set chunkload to 2, then the file should indicate 2/2 but it only stays at 1/1.

I have tried flashget to download from uploading.com, the speed is very fast around 890KB/s even with one chunk but in JDownloader it only gets around 40KB/s. Bad thing about flashget is non-consistent downloads - file turns out to be get.php most of the time.

How can I make the chunkload in JDownloader working for uploading.com.

Thanks
