waiting here since hours without response.
Hi,
You should be able to purchase the FormsCentral (Basic or Plus) subscription via the adobe.com store.
Here is the link to the page in german: http://www.adobe.com/de/products/catalog/software._sl_id-contentfilter_sl_catalog_sl_softw are_sl_acrobatcollection_de.html
Hope this helps,
Thanks,
