Changing Spark skin

Hello.

I have such problem,

In our company now is being used the spark clinet, which skin was changed and the client is named somewhere else… not spark,

Now I need to install spark client in the same pcs in our natwork, with differnet openfire server, and other IP, all working right, but

when the user starting work and loging in windows which spark he opens first, in the saecond appers that IP. I need to intagrate this program with taht other and whanted that each of tham have there server IPs, and do not desturbe each other.

Could you halp me please…
