I don't think MG will be issuing refunds, but you can inquire with them. We will be releasing a free and unencoded version of the module with no license validation. I suggest continuing to use the one you purchased from MG until we release the open version, which will likely be later this week.
Sorry for the quick double post but it seems to have been fixed after I updated the IPN information to send IPN messages and changed the URL to the path of Blesta (https://www.anzensolutions.com/accounts/ in my case).
I apologize.
I did have to manually resend all of the IPNs though that were marked as disabled. To do this go to Settings -> My selling tools (in PayPal). Click on "Update" on the right side next to the Instant Payment Notifications section. Click on the "IPN History page" link near the top of the page that pops up. Then select each one that is marked as "Disabled" then click "Resend selected". It may take a few minutes but now my invoices are being marked as paid. <3
They made an agreement with WHMCS to only sell their modules and so signed the Blesta module over to the Blesta team. The module will become a standard part of the installation in the future.
Virtualizor is assigned to task CORE-419 and tentatively assigned to 3.2. It's possible it could be pushed back beyond this depending on need and workload for 3.2.
Blesta doesn't yet, the modules in development are the ones most of their customers need, they are ranked in priority. I believe they was looking at that though so only in a matter of time before they probably start on one.
