If the following occurs:
1) User can navigate to the CampaignMax home page
2) User can login and get to the split screen
3) User sees nothing but a white box where the menu tree should be

Then, it could be due to an obsolete version of the Infragistics TreeView control being loaded on the machine. To remove the obsolete version follow these steps:

1) First we must find the obsolete version. It will commonly be found in c:\winnt\system32\sstree.ocx. If it is not there, search the local hard drive until it is found.
2) If you cannot find it on the local drive (very uncommon), then you can search the Registry for the following entry 1C203F13-95AD-A84B-00A0247B735B. When that node is found, look for a child node named InProcServer32. This entry will have the path to the SSTree.ocx file.
3) You must now unregister the control on the machine. The remaining steps explain how to do this.
4) Click the Start button and choose Run...
5) Type the following command: regsvr32 /u 'c:\winnt\system32\sstree.ocx'

NOTE: If you found the sstree.ocx file in a different location, use the path where you found the file. You must include quotes around the full pathname if the filename includes a space.

6) Click the OK button. You should get a window confirming that the control was removed successfully.
7) Run CampaignMax as usual. When you get to the split screen, the menu should load automatically.

NOTE: Your machine may prompt you before installing the control. You must allow the control to be loaded or CampaignMax will not run.
