Does anyone know where I can get hold of a download for the ETKA parts manual ! , or the CD , I have 7.3 but it is not now working on my pc , I think thia is after I put in another hard drive and put windows 10. 64bit on it , the other drive has windows 7 . 32bit , that is the drive I had the ETKA 7.3 on , but it will not work anymore .
