PLEASE HELP FIX THIS – WPS Office Review

I am a senior on a FIXED income. I have an iPad 2 and was happily using your app when I updated it in June and instead of being able to access the older version, which I have been able to do, I'm not not able to open it at all. Please help me regain access. I cannot afford a newer iPad. Thank you.
