HELP!! Technical Problems

HELP!! I'm new to this forum so please forgive me if I am not posting in the right section.

Do you guys have a trouble shooting/technical problems section in this forum?

My problem is I have just recently bought a copy of Medieval Total War (Gold Edition) which includes the Viking Invasion pack but it will not run for me.

I have a Pentium 3 with 933mhz processor, WinXP Home (SP 2), and GeForce 2 graphics card and I am well over the specs to run the game. But when I double click the start icon the screen goes black for a few moments and then a warning dialog appears telling me the I am running a debugger and the game won't go any further.

How do I know if a debugger is actually running and how do I deactivate it?

I am dying to try out my game and I'm getting very frustrated as I have tried everything. I hope someone on this forum can help and again my apologies if I am posting in the wrong section of the forum.

Many thanks in advance.
