well... there is an idea..
1 - extract all skilldata_xxxxenc.txt files from your media.pk2.
2 - decrypt them all to text files.
3 - go to your DB and execute this query on your SHARD DB :
Code:
update _RefSkill set service = 0 where Basic_Level = 12
**Hint: this query will disable every lvl 12 skill in your DB**
4 - now after disable all lvl 12 skills execute this query :
Code:
select * from _RefSkill where Service = 1 and ID <= 4999 -- for skilldata_5000
select * from _RefSkill where Service = 1 and ID between 5000 and 9999 -- for skilldata_10000
select * from _RefSkill where Service = 1 and ID between 10000 and 14999 -- for skilldata_15000
select * from _RefSkill where Service = 1 and ID between 15000 and 19999 -- for skilldata_20000
select * from _RefSkill where Service = 1 and ID between 20000 and 24999 -- for skilldata_25000
select * from _RefSkill where Service = 1 and ID between 25000 and 29999 -- for skilldata_30000
select * from _RefSkill where Service = 1 and ID >= 30000 -- for skilldata_35000
**This query will generate 7 groups of results every group is a skilldata text file**
5 - now copy every part to its text file (replace all old lines in each file) and encrypt every file back and everything is OK..

I hope you understand the idea and you can do it without errors..
