Unfortunately it would not be until monday, at least (I don't know what their response time is). If you don't hear back by tuesday or wednesday you could email them again or send a private message to Lynn.
If you are in North America, there is a 6 or 9 hour time difference, so late monday in Belgium could still be early monday for you.


You could keep playing with your current save (in that case maybe email Larian again saying you'll send another save late Sunday, or something), but because you didn't exit the building as intended you will have problems with your dragon stone (see Dragon Stone is no longer working).
