PS: sorry for my english...

If you have only had Hammer for 2 days, check out the links in this post first.

Only when you are completly confident and able to do the things asked for in the links in that post, should you attempt to do anything Portal related. For any Portal problems, first check here and here. Most problems can be solved by checking these links. Only after checking these links, if you have not solved your problem, should you post asking for help.
