Oh sorry, its working now!
Although, the ids in the xml are wrong (?), I only checked the names.
For example:
<upgrade id="4" item="902,10" materials="91384,1" adena="10000000" result="91378,0" /> <!-- Queen Ant's Ring Lv. 4 -->
902 is Phoenix Ring, and I had Queen Ant's Ring Lv. 3.
Thank you for your answer, please close it.
