I'm having the same issue with my GUI wallet hashing, but not collecting coins through alloypool. Can you post a tutorial of how to switch mining pools? My efforts to change pools have been unsuccessful.
When you are in GUI wallet, you need to go to Mining tab -> the lowest one on the left. In Mining tab you have list of pools, you need to drag the one you prefer to the top of the list. If your prefered pool is not on the list, or data is incorrect you need to manually add new pool at the bottom... and that is pretty much it... just remember the pool you prefer have to be on the top of the list...
