OF crashes!?

[The Gnipper 0]

Ok, so i used to play OF on my W98SE machine fine (bit slow due to processor etc. etc.) - its an original . Then i upgraded to ME - new HDD etc. Now ive re-installed OF but when i complete the mission the game throws me back to desktop.

Ah. i thought - i need to patch the game! So i got a copy of the 1st upgrade and tried to install it - with the OF cd in the drive. It whirred and up popped the logo - then nothing - back to desktop.

This is really starting to annoy me cos i cant get past the tank training mission!!!!!

My specs are

AMD 1.4ghz processor

256mb ram

Matrox Millenium G400 32mb GFX card

Windows ME (fully updated).

If anyone can help me you'll make my Christmas!

Thanks in advance
