Adobe PDF Pack Compress FIles

Hi,

Hi, I have just purchased to a subscription to Adobe PDF pack with the requirement to compress a number of scanned pdf files. I successfully did a high compression on 3 files but was not happy with the quality, so decided to process the uncompressed files again with a Low compression.

However when I try to compress the files again I get an error that the files are already compressed.

I tried renaming the original files and still get the error.

Any advice appreciated.
