method to install old version of an app?

hello

I have a rooted kindle fire. until today I was using an app called ras mobile (version1.3.1) and which worked great all along until I was stupid enough to update it to version 1.6 today in the android market. it now just crashes hopelessly everytime I run the app.

is there a place on my kindle where the old apk is stored so that I could just reinstall that? I have looked all over the net for version 1.3.1 or lower but I keep getting redirected to the android market which only has the most up to date version. very very frustrating that the "update" has killed a major use for my kindle.

I never backed up anything prior to this update, this update really has messed me up.

thanks for any help

 

thanks for the reply, ive searched high and low for any other version of the app but none are to be found anywhere. every single search ive tried brings me back to the android market.

ive now also emailed the developers 4 times since Monday without reply. very frustrating since ive bought 4 of their dvr machines in the last 5 years at a cost of nearly 20,000 eur
