I visited my parents.
But the desktop over here has some problem to start OCTGN.
Here is the log.txt file.
Please let me know how to fix this situation.
Haha. glad it worked.
Yeah, you had two separate issues in your log file before. Deleting those files fixed the one problem you had, now you need to do one more thing.
Follow the instructions here. http://www.sitefinity.com/developer-network/knowledge-base/details/this-implementation-is-not-part-of-the-windows-platform-fips-validated-cryptographic-algorithms-exception
After that, go ahead and try and launch again and let me know how it goes.
It looks like your game database is all messed up. Maybe not the whole thing, but just one game it looks like.
Go in and delete the folder C:\Users\sikai\Documents\Octgn\GameDatabase\a21af4e8-be4b-4cda-a6b6-534f9717391f
(Don't worry, this won't delete your images)
Then you should be able to start up octgn.
Looks like your operating system won't let OCTGN write to the C:\Users\like\Documents\Octgn\Garbage directory, and probably others in that area.
