Does SAP still support the Crystalreports.com plugin app for Salesforce?

We currently utilized the Crystalreports.com plugin for our Salesforce environment, but about a month ago the plugin crashed. The plugin crashes immediately upon activation (screenshot of error is attached). We've attempted a re-install of the plugin, but no progress. Also, we have contacted Salesforce and they directed us to SAP the creator of the plugin. We're coming to the conclusion the plugin app may no longer be supported by SAP?

Any assistance would be most helpful.

Thank you
