Would you please some one help us to solve our problem,

we have a forum and we move to new domain name more than 3 month, our pages index in google but when we search our address in google like "forums.parsforums.net" we don't see any thing,but last night again we change the domain name add suddenly we added in google and when we search the forum in google we see the result in first line,it can be cause of the bad instaling of vbseo? ,i think we have problem with vbseo installing,
