First of all I would like to say that I'm a french dude from Montreal so I will try my best to explain my situation.

Here is my story
I have a Creamware Minimax ASB synth, and I've made a mistake updating the firmware (MINIMAX_ASB_OS_2_00.ldr) without entering the correct and non generic activation key code.
Like many other user:

So I have received a serial key code from Sonic Core to update the firmware with my current Macbook Pro but an error occurred ( Failed to create a temporary file name (error 13 : Permission denied) and was not able to perform the update.
So after this I have tried with my older Mac G3 PPC mac OS 10.4, the writing is completed but It the same E1 error code is showing when I power on.
I also tried with PC computer Window 7 Windows XP but the same thing happen. windows 7 the same error occurred (an error occurred ( Failed to create a temporary file name ) and Windows XP the writing is completed but It the same E1 error code is showing when I power on.
I wonder if my code is good and what I am doing wrong. I was thinking to open the Synth and remove the battery memory to hard reset the device.
Could someone with a big heart help me, !!??
Please
I know that Ralf was the man for this but he doesn't work at SC anymore.
my last option could be to manually insert a new Eprom with the OS on it.
