unable to open an .acsm file (related to an ePub file to be downloaded)
though title of eBook is displayed in media shelf
error code "E_ADEPT_DOCUMENT_TYPE_UNKNOWN" appears
Adobe Digital Edition closes
check: my Adobe-ID ist ok, verified
test: other ePub-files (e.g. free ones from Adobe) are displayed
I asked publisher of purchased ePub to create a new .acsm file (in case of damaged file)
BUT: second version of book appears as a titel

Adobe Digital closes down.
What to do?
