Blackcat USB won't run with SB5101 properly

[deathroll]

Loading script: DPC2100_JTAG.bcs
Setting device parameter (Intel Flash delay) to 0x32
Setting device parameter (AMD Flash delay) to 0xAF
Setting device parameter (Memory Read Delay) to 0x32
Error in script DPC2100_JTAG.bcs on line 19
Reason: error parsing command: if not (Memory(CFGFLASH).Exist)

I tried to load 2100 script but it doesn't work too. Sorry i don't understand your words in brackets

By the way i didn't subscribed with that modem. I didn't plug coax ever. This is a new one. Could this be the reason?
