If you marked the mods as installed, you can see them in your usercp.
As far as help with the mod, you need to find and ask in that mods thread.

Questions/Problems regarding modifications/styles need to be asked in the modification/style thread. That is where the support for modification/style is - not out here in the main forums. Please note that if a modification/style is unsupported (or even if it says it is supported), you may be on your own if you chose to install it.
