I had no poblems earlier receiving my pin....that was about 9-10am or so when I checked. Since then I've been in and out of EG all day I haven't been requested to receive a pin again so am not certain.
I would say if you haven't received it in a an hour or so to try again and see if a pin pops up. There's been times it took almost a day or 2 that I finally received a Pin #. For some reason it happens every so often where they won't come right on time, but if you keep trying eventually one should come

If anything then I would suggest contacting them for assistance.
Good luck bakong!
