When asking for help at the community help section. Explain what type of error message you are having as well as a print out of your system specs. You have to open up and explain what is wrong to get help. The moderators there are very helpful. Most members are here as well, even though at timesl they don't get along .
Don't get confused. The mega stuff is a mod. They will not help if you have installed a mod here or there. Uninstall everything and begin again. Make sure everthing in your folders are uninstalled or deleted. Correct your registry with a registry cleaner and begin again.
If you are having install issues, post at the community help section and help will soon be on the way. S!

Also the most basic. Check the minimum system requirements. I'm not a tech guy so sorry if I'm not able to help you dx your problem and help you get into the virtual skies. Ps. try to limit the size of you pics. They tend to get upset do to the rules on limitation.
