Hello ravaj!
IMO :
1. Reinstalling the game is the best sollution. (I prefer to delete the current Seal Online Blades of Destiny folder first.)
2. Ask anyone (friend or family who also played the game) for pre-installed copy of Seal Online Blades of Destiny.
3. Re-update the game from version 284 by the following steps :
  • Find a version.ini file in Seal Online Blades of Destiny installation folder then double click on it to open the file.
  • Replace everything inside it with :
    Code:
    [DEFAULT]
CUR_VERSION=+/a6lpTK8YM=
  • Don't forget to save the changed.
3. If the solutions above doesn't work for you, Submit a ticket to Playwithi Support to get more help.

Cheers!
