E_ADEPT_DOCUMENT_TYPE_UNKNOWN (former answers in forum didn't help)

[arnek71522036]

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

but still ePub file can't be downloaded or displayed

(loading process window in Background being coverd by error code window "E_ADEPT..."

Adobe Digital closes down.

What to do?
