How to Remove all Vestiages of Photoxhibit?

In the last few days, I experimented with the Photoxhibit plugin, then deactivated and removed it. I then tried the Lightview-Plus plugin and couldn’t get it to work. I’m wondering if something might have been left over from Photoxhibit that would have conflicted with Lightview-Plus. I’ve written the author of Photoxhibit to ask if any remnants are indeed left over, but haven’t heard back from him yet.

Out of curiosity, I reloaded Photoxhibit, and when I look in its admin settings, my previously created albums and galleries are showing. So that seems to indicate that all its components were not completely removed by simply deactivating it and removing its directory from the plugins folder.

Can anyone tell me how to clean up all the Photoxhibit files after uninstalling it? Thanks!
