Wytron CD-298 problem.. only partial duplication

Does anyone have any advice on an old Wytron CD-298 that is only copying CD’s halfway and then stopping ?

I am on version 2.68 firmware.
I also can not find a link to the latest firmware 2.85. Any info on where to find the firmware would be great.


Just fill out the form from the wytron support website www.wytron.com.tw/chinese/ and they should send you the firmware
