USE_TXENABLE 16F1783 timeout

[petspats]

Hey!

Thank you for the great software.
It works great:

Initiating write...
Searching for bl . . . . . . .
Found PIC16F1783 fw ver. 1.0.2
Waiting for the boot loader to be ready...ok
Hex file successfully parsed
Writing flash....ok
Tx 387 bytes / Rx 14 bytes / 4,4s
Write successfully completed

However when i enable USE_TXENABLE it will just time out:

Initiating write...
Searching for bl . .
Found PIC16F1783 fw ver. 1.0.2
Waiting for the boot loader to be ready...ok
Hex file successfully parsed
Writing flash....response timed out
Write flash failed
Tx 8 bytes / Rx 4 bytes / 30,9s
Write failed

So how could i fix this?

Hoping for help.
