HELP - Site Administrator´s password is lost.

Hello there.

I need get a new password (or re-set) to ARIS Site Administrator / ARIS AdminTool 7.2., our last ARIS administrator left the company and changed this password.

Is there some way to change again??

I saw that in the server, in the confing files, there is one that has a parameter with siteadmin password. (but I'm not sure)

Someone knows if is possible change the password in this file??  or Someone knows where change this password.??

Thanks in advance.

David.
