can't post a question

I get a red banner, saying I can't update or create content when I try to post this question:

Using H&R Block Deluxe software on my MacBook Pro has been a nightmare this year. I've used Block software for years with no problems, but this year has been a bear. This is the first year, of course, that I've had Yosemite as my operating system. I initially couldn't save/open my return using a CD I got from Office Depot. I got an error message: "string ID insertion failed." Block Customer Support indicated the program ws corrupted. In talking with the Block rep, I picked up on her total unfamiliarity with Yosemite. She was only aware of the "cat" operating systems. I uninstalled Block and installed a download provided by Customer Support. I was able to complete both federal and state returns and successfully transmitted them. I got the message in my e-mail that both returns were accepted. My problem now is that when I go into the program and try to check the status, I get the same error message about an insertion error. I had saved my data in three different locations, including a flash drive, just before I filed, but I get the same error message when I try to open them. So, I have no acces to my 2014 digital return. Block Customer Support is telling me my returns can't be retrieved. This is the first time I've been in a situation where I have 3 back-ups of a file, but am being told the data is hopelessly lost.
