You could be facing problem in Installing themes which you have downloaded due to certificate issue, you can try following steps to see if it helps you:

1) Go to menu-> installations ->app manager -> options -> settings -> and change the software installations to all.

2) Check if your downloaded Theme files are of ".sis" extension and they should be S60 3rd Edition theme files.

If you own Nokia E-series mobile phone (E60, E61, E70),
you may want to do following in order to allow phone
to install SmartMovie:

1) Open Application Manager
2) Choose Options, then Settings
3) Switch Software installation to *All* (not Certified only)

This will allow you to install non-certified applications.

Certificate expired is when the theme has expired, best thing to do is look at the date of the theme before you download it so you won't have this problem.
Try mobile9 website they show the expire dates

Good luck
