Where do I get patches greater than hotfix #3 for the offline version?
There is none available to download, and also for the normal gog version, no greater update gets installed foe me :(

Currently I cannot continue due to crashes...

Contact GOG support.

Patch 3, Hotfix 3 is the current version. There is no newer version.

The launcher talks of hotfix #9

Steam/Larian - Patch #3, hotfix 7, hotfix 8, hotfix 9

=

GOG version - Patch #3, hotfix 1, hotfix 2, hotfix 3

(GOG just re-numbered every time there is a new Patch#)
