Achievement sucks

The goals are good, but the storage system sucks.

Lol, they've released some patches trying to fix it. Just cross your fingers that it doesnt wipe your stats, that would be worse

I got this issue too
go to C:\Program Files\Steam\steamapps\%username%\portal\portal
make a new folder and copy into it 2 files portal_gamestats.dat gamestate.txt
Start a game and you could achieve those achievements. I have to do only one test and I get achievement at once.
Ps:I found it NOT steam support :/

It worked! Thank you very much.
