Your problem is a plug'n'play(tm) paperclip, luckily almost all the plug'n'play(tm) material is in the surface of the wire. All you need to do is sandpaper the paperclip to remove the pnp coating and try again.
The totally plug'n'play paperclips are easy to spot as after a few seconds of vigorous rubbing, a large ammount of the paperclip will have worn away.
Please note any "rough hard surface"(tm) will do, as no manufactures of rough hard surfaces have managed to manufacture a pnp surface coating which is hard wearing enough to withstand the normal wear and tear which rough hard surfaces are subject to, and as we know to make the whole "rough hard surface"(tm) pnp is still too expensive.
