I have my old copy from 4.11 and I got it into my new PC, i downloaded 5.1.4 and tried using the restore option, however it said it couldn't indenify its version. The file i was using was a ZIP file. The message I got was something like "The version cannot be determined. Regarding the update process: for version 2.x (as well as 3.0 beta), you must first update to version 3.x. Subsequent updates can be performed later.". I tried maybe downloading older versions but they didn't launch. Why can't it...
