bbx wont read the engine tune

[restless@westnet.com.au]

hi guys
i have a slight problem v2 not reading the engine tune says error #050B script file not supported by current ver ??
Ive just downloaded the latest up grades v7.5 and v8 and up graded the firm ware and boot block on the v2 ( wouldn't work with the old ver aether)

all so i cant drag a tune file straight into the v2 from explorer any more ? says its not a ctd file ? it will go in but wont show up on the tune list on the v2 but does show up on tune in explorer ?
its been about 4 months since i did any thing with the v2 and the car, was all good before
i can up load a tune with pass through with the v2
but the v2 still wont read it after its in the ecm ?
cheers
