I am unable to download the update from the app store. There is a "hash mismatch". The previous version is excellent though.

Version 2.0

Like Bravecat advises - the dreaded "Hash Mismatch" problem - strange thing is if I delete the original app I cannot then find it on my purchased list.

Has it been renamed?

Please advise....


I was able to get around the problem by deleting Light Compressor and then downloading the app again. As far as not finding it in your App Store dld list go to your account under Quick Links and half way down you will see iTunes in the Cloud and to the right of that is hidden purchases. It might show up there. Good luck.
