1. Try repairing your Excel install - go to add remove programs and select Office 2007 - repair this
2. Run Excel diagnostics - Excel options, Resources, Run Microsoft Office diagnostics
3. Try uninstalling Excel and then reinstall
4. You can try registering the controls and the user form - try downloading from http://www.ocxdump.com/ MSCOMCTL.OCX and MSCOMCT2.OCX - place them into C:\WINDOWS\SYSTEM32 if you are using WinXP. Once it is there click START--> RUN and type "REGSVR32 MSCOMCTL.OCX" (No quotes) in the box. Get the calendar control for your version of Excel MSCAL.OCX and register this as well.
Depending on your operating system/Excel version will determine where you place OCX/Which OCX to use. Google is your friend.
Try the easy options 1-3 first before going down the track of registering the various controls
