Someting new here:
I love skyrim, i love elderscrolls, i love bethesda for their great job, and ok .. something got messed up with that latest add-on.. but i can not understand why their are so many "fans" reacting that way. i am a german (bytheway:sorry for my bad english) games developer myself and bought dawnguard on tuesday .. and after 60 minutes i noticed the bugs. ofcourse i was disappointed, but i never felt deceived - because bethesda is an enrichment to videogames and to my personal entertainment for many years ! ... it would be very, very unfair to go on a rampage now. the bugs are posted ... it would be a nice gesture to leave it at that and just wait a few days for the patch.
so please calm down, i am sure , they are working 24/7 to get dawnguard working and afterwards you will love them again for their great work

i think it will be patched very soon... i am looking forward to a great addon...
