Default upgrade boot loader (SPL)

Hi guys,
I have an unlocked MDA vario II, which I unlocked it by myself using the CID unlocker 3a. After the procedure which was succesful, the SPL of my PDA changed to these:
HERM 300
IPL-1.01

HERM300
SPL-1.40 Olipro

I tried to upgrade the SPL with the new HARD SPL v7
and I am getting the error 269 when I am using the RUU wrapper.
What is the problem ?
will I be able to install new roms with my current SPL ?

(sorry for this post but I dont have enough time to read arround 100+ threads in order to find assistance)
