Echo:
Did the UPloaded Screen look like this:

Did you check the "cart" how much you have to pay BEFORE paying?

Could you please upload that strange Jar file for me? The payment process usually has no Downloads at all.
Can you please check and save your browser history (screenshot or as text) of the payment process.
Please check your browser download panel and tell me where you downloaded this jar file (Url)

Where did you get this link from: ....RM-P4 ?
Can you please create a JDownloader log for the time of buying?
Thanks
