Update 8/26: DialCentral now seems to be fixed. Mine is, at least. If yours is still broken, check out the link below for more information. You might have to manually change a file in order to fix it.

If you are running DialCentral on your Nokia N810, you need to be aware of this:
The latest version of DialCentral has some bugs that cause the program to not work properly. The developer is working on a fix.
For now, if your N810 asks you to install updates for DialCentral, don’t allow it or it will break the program.
