Export midi via email

I bought the app thu the App Store to use on my iPad,BUT I cannot export (midi capture) to my email to use on my PC [DAW)…I tried every combination and it HAS worked on the odd occasion,but not many times.I contacted Plug-in Boutique to get my other licence for PC ,but they only deal with pc? So how do I get this? I bought the iOS version and have the receipt so I’m not buying it again…every other app I have can email/transfer wav files around but not this one?

License for the iOS and a license for windows are 2 separate licenses. Buying either one does not give you a license for the other. No where does it state this.
