Do I need Specific Mgcamd for a specific Image to unlock Bulsat?

I hope someone can help me because im struggling abit

I currently have a DM800 Ferrari Clone and im looking to watch Diemma and Novasport on Bulsat (39E).

The image im currently running is Nemesis 2.4 (latest I believe).

Now if I understand correctly you used to have to run a modified version of Mgcamd 1.35a to clear Bulsat. My questions are:

1) Do I still need to use the modified version of Mgcamd 1.35a to clear bulsat with the latest keys or are the latest 1.36, 1.37 and 1.38 compatible with bulsat and will also clear it?

2)Do I need to install a specific version built for Nemesis 2.4? If so which one?

I have tried the main modified Mgcamd 1.35a in this forum, also version 1.36, 1.37, and 1.38 from the extra url in Nemesis to try and clear with the latest key file (Kargo25s from 9/01/2012 Today) with no luck. Has bulsat changed it keys than the one in the key file?

Thanks in advance for your help and expertise

Thanks for the quick reply. BTW what key pack do you recommend/use?

Also is Bulsat clearing for you at the moment, or have the keys expired in current key packs, and we are currently waiting for new ones?

Thanks again

Thanks Tom but thats not really answered my question. Are the channels stated (diemma and Novasport) still clearing on the keys in current key files?
