Upload Admin Tools error -MJ not in components

Hi - I had trouble uploading the tar.gz folder in both Firefox and Chrome and decided to convert it to zip after reading a similar experience here on the forum. Though the install did say successful it also gave an error message regarding Admin Tools (I apologize for not having noted down the exact error message but I believe it was Admin Tools not installed/updated or something to that effect).

Now I see the various MJ plugins and modules but do not find MJ in my Components dropdown. I am using Joomla 1.7.Would greatly appreciate any advice/guidance.
