You need a new unlock code every time you change some significant piece of hardware in your system. Did you install/change any specific device during the last two days? A new video card, a new sound board, a new hard drive?

Its best to leave that setting on normal. If you want mipmapping set it in the Glidos options.

But that doesn't quite fix your problem. If the setting is making the logo appear then unlocking went wrong somewhere. Probably best thing to do is play until you get to the later levels, where the logo will appear independently of that setting, and then go through the unlock procedure again. If you run out of your unlock allocation, I can add more.

i have a notebook Olidata Tehom.
Yesterday i have re-installed xp home ,single partition , but non have changed any hardware.
Thanks for rapid reponse
