SOA and TOB wont start up

[Fitz]

After not playing SoA or ToB for while I came back to them last night to fire them up and maybe solo through but I kept getting the same error. The error doesnt say anything, its just quite small box that says "error" on top of box in the blue header and in the grey space below there is no writing, its just blank. I tried all 5 CDs (4 from SoA 1 ToB) and none worked. The only thing i really tried other than that was restarting which had no effect, i was going to reinstall but thats a pain so if there is an easier fix please lemme know. Pre thanks
