Supernova/Lexicon Research not working

[Josaiha]

Is anyone having any issues with the Research skill since Kunark came out? Am I missing something stupid?

I am trying to Research the lvl. 49 wizard spell, Supernova, as a lvl. 50 wizard with 175 research skill.

I've put the Rune of the Astral and Run of Impetus in my Lexicon, but when I try and combine it I get the message "You cannot combine these items in this container type!". I tried with other runes and the same thing happened. I also bought a new Lexicon, but still getting the same result. I never had any issues with researching spells prior to Kunark launching.

Thanks,
