Make sure that you did not accidently download a Kindle version (sounds like you did not) of the ebook in question if you are using an iPad, Windows, or Android based device. The Kindle ebook files only work on a Kindle device.
Also, if you are trying to read this file on a Kindle, pdf files will not read on thsse devices.
An acsm file should be readable if your device is Windows, Android, or Apple operating system.
If none of these scenarios are the case and nothing is working please bring your device to one of our library locations so we can see what's going on and assist you directly.
