Impossible to save or send my Quickoffice Pro documents

Hi!

I have a big problem for to save or send my Quickoffice Pro documents.

I had been using with no problem this program in the last two years, with a old IOs version in my Ipad 2 (6.x.x)

I had actualize my IOS to 8.1.3 and after this moment I can´t save, send or do nothing in this program because it closes in the moment I do something with it.

I had been looking for a solution and I had found that the App Store has retired this program (buyed for Google), then I can,t ask for the App support.

Please, tell me a solution if somebody knows because I had a lot of works and information in this doccuments that I can,t lost.
