Events + plus goes to a 404 page when configuring

I had events + installed fine on my server then moved my install to another server for the client and even after reinstalling fresh a dozen times I get a 404 error when configuring the main components such as which page the event payments are found and event registration. The site is showing everything as it was configured on the old server but now it shoots me over to a wp-admin/admin.php?page=configure when i confirm my changes which prings up a 404 page not found. What could be causing this? The site is I would LOVE help on this. Thank you so much ... you guys have always been awesome!
