DFU bootloader recieving 1024 FS transactions issue

DFU bootloader question. I currently have an issue with using the LONG_RECIEVE_TRANSACTION define. If the set this define my setup stage and all my 1K byte data transfers is received wt ACK (note I'm the DEVICE) but the status stage data is not sent and all I see is NAK being sent by the SIE. If I turn off the define and set it back to 64 byte it works. What is missing for LONG_RECIEVE_TRANSACTION to work? is there any new updates to the DFU bootloader code?
