What exactly was/is 'corrupted or something' ?
Try redownloading whatever it was and unrar it with the latest version of WinRAR.
My starter kit includes all you need to convert your MAME/NeoRageX ROMsets to .AES (including the latest prefetches and an updated ROMRC) - look for 'ncGui.exe' in /AES-Workplace/Convertneo/ (and place your zipped games in there too).
