Used to work, not anymore

I have used this application previously and have not had too many issues. Now it won’t send my 2 page fax. I get “invalid parameter” error messages and it is crashing when I click on the country of origin for the fax number and on various other activities. I’ve spent almost an hour trying to get one 2 page fax sent unsuccessfully. I gave it two stars because it used to work. I have lots of unused credits for an app that doesn’t work. Time to find another application for faxing.
