I had to rebuild my site after all the changes to Multisite and security plugins

Ok, so after having a Multisite and trying out some security plugins and then switching back to a single site my DB and fileserver became loaded with extra "Crap" so I re built my site and imported everything else. doing so made some of my site links on google etc. dead example: http://techandgamingnews.com/blog/tag/top-25-fury-warriors is now http://techandgamingnews.com/tag/top-25-fury-warriors

is there a way to fix this. or should I just wait for the new links to update?
