If you mean that SD Central crashes during the "checking for new and updated threads" process.... I had this problem for a while myself. I got this fix from T-man himself.
1.) Close the stardock central browser.
2.) Go to C/program files/Stardock/Stardock central/discussion. Select all the discussion .ini files and delete them.
3.) Then start Stardock Central again, and when it connects to the Stardock servers it will automatically re-download the .ini files again. This should stop it crashing whilst updating.
If it does not automatically download the .ini files, right click on each of the WC General, WC Help, and WC Skinning buttons, and click on reset list for each one. This will download each .ini file manually.
Well, this worked for me anyway...
If this is not your problem, then obviously..... disregard this post.
/me hopes he's not giving bad advice here....
If anyone knows better, please feel free to jump in here... (just trying to help)
