There is absolutley no need to put phpmyadmin in the same directory, infact there is no need to install it at all, as the version provided by your host will work just fine and is outsied of your webroot and therefore harder for hackers to get at and is the recommended way to go.
Installing it into the zencart directory will overwrite zencart files. Just don't do it.

see down the bottom of this page there will be similar threads, they may have more info on things to do, repairing it should fix it, unless there is something else coming in to play

I also installed phpmyadmin onto the directory where the shop is located and now everytime i put in the normal link to the shop it brings up the phpmyadmin
