Happy to announce the PP issue got solved "by timeout" (180 day rule).
Thanks to everybody for your support with this, and sorry for the inconvenience and delay caused by it all.

We're considering whether to offer a different product via PayPal (after approval by PP), somthing like "download of all documentation, project files and schematics", with only a sidenote that we will grant a rebate in same amount on the price of final product Neo900 device.

cheers
