First of all my HP died, shop tells me MB bad. I go and find new computer because I don't have time to wait for a new MB to deliver (I'm a college student, no time to waste or wait). so I go last night and pick up Lenovo H series with Windows 8. I had a WD 1TB HD for back up on the HP. I plug in the Wd to the Lonovo. I get the files to DL but now when i try to open them I get a popup asking what kinda program to open XTML file. I have no Idea? Does any one have a clue, since mosat are smarter when it comes to this type of problem than me. Thanks.
