Somewhere in the code u should have getBuyStoreCurrency defined.

You have a simple error, you try to put a long into a int.

 

Define _playerAdena as a long type (in PrivateStoreListBuy) :

 

- private int _playerAdena;
+ private long _playerAdena;

 

-----

 

Or modify getBuyStoreCurrency() method to be an int type (in L2PcInstance).

 

- public synchronized long getBuyStoreCurrency()
+ public synchronized int getBuyStoreCurrency()

 

-----

 

It's fully depends of the chronicle I think, if from basic you got an int type, an int type is enough.

 

DON'T MODIFY BOTH CODES, YOU WILL HAVE EXACTLY SAME ERROR ELSE.
