Is it the MD Comptroller's fault that we can't e-file extensions? Or has ProSeries not updated their system?

If we weren't going to be able to e-file the extensions or payments, I would have hoped that ProSeries would have been professional enough to send an alert when they knew about this problem. To have an e-file error that states the filing season has closed, when it hasn't, is not helpful to anyone. Will we be able to file previously extended returns electronically? Is anyone working to resolve the problem?
