Rok Box CDrom not responsive/not working

If your CDrom for your Rok Box shows as a problem device in Windows device manager, or doesn't load properly when inserting a CD/DVD, the issue may be due to corrupted registry entries for the device. 

Follow these steps for a resolution: 

1. Press the Windows logo key + R to open the Run dialog box.

2. Type regedit in the Run dialog box, then press Enter. If you are prompted for an administrator password or for a confirmation, type the password, or select Allow

3. In the navigation pane, locate and then select the following registry subkey:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

4. In the right pane, select UpperFilters.
   
   Note You may also see an UpperFilters.bak registry entry. You do not have to remove that entry. Click UpperFilters only. If you do not see the UpperFilters registry entry, you still might have to remove the LowerFilters registry entry. To do this, go to step 7.

5. On the Edit menu, select Delete.

6. When you are prompted to confirm the deletion, select Yes.

7. In the right pane, select LowerFilters.
   
   Note If you do not see the LowerFilters registry entry, go to the next method.

8. On the Edit menu, select Delete.

9. When you are prompted to confirm the deletion, select Yes.

10. Exit Registry Editor.

11. Restart the computer.
