Good day. 
  
 I was trying to work with 'buyingstore' but it didn't work. According to Hercules Wiki, They said I need a client version 2010-04-27aRagexeRE or newer. For this reason I want to know my client version so I can figure out whether it's client or source problem. 
 Would you please Teach me if you know? 
  
 Thank you.
