install exited abnormally -- recieved signal 15

[fam. Willemen]

Hi guys! I really need my server back online very soon, but the problem is it crashed and (also because I had a few more problems) I decided to re-install redhat and now 7.0 instead of 6.0 on a empty drive. Just after starting the install, I get this error:   **** Running anaconda - may take some time to load... install exited abnormally -- recieved signal 15 sending termination signals...done sending kill signals...done etc.... **** Could somebody please help me?!
