cDir persists the configuration data in a file called cDir.ini under the Resources folder.
If insufficient file access rights are granted to the identity under which the cDir application runs, it will fail to persist the data.

Follow these steps to fix the problem:

1. Find the identity under which cDir runs (in IIS Manager, look at application pool level>>Properties>>Identity)
2. At the file system level grant Write rights to the above identity for the Resources and Logs folders.

First check this website to see if we have released an update that supports your new device. We typically release updates for the most popular devices, as we did for Apple iPhone/iTouch, and for BlackBerry's Storm, Odin, Tour and Bold. You can also contact us to check if we are working on an imminent release.

If we have not released an update or you want to "tweak" cDir to do your bidding, you need to add the new device model to the Web.config file stored under the root of the cDir application. The following describes how to update for a new BlackBerry smartphone:

1. Locate the browser capabilities element, called <browserCaps>.
2. Within the browserCaps element go to the first <case> element that matches a BlackBerry device.
3. Within that case element go to the <filter> element.
4. Locate the last <case> element within the filter element. Select, copy and paste it just before the closing tag of the filter element (</filter>).
5. Modify the pasted case element to reflect the settings of the new BlackBerry device.
