V 5.03 - Invalid Digital Signature

[eboie]

When installing V 5.03 in my Pearl 8120, the Desktop Manager gives the following error, "The following modules could not be loaded because their digital signatures were invalid. com_dcco_app_iSilo.cod"

Please provide a valid signature. Thanks!

Is this the first time you have ever installed iSilo on your 8120? Or were you able to install a previous version successfully?

Does your BlackBerry device sync with a corporate server?

The most likely cause of this problem is that your handheld is configured with an IT Policy that does not allow third party applications to be installed. On your device, go to Options/Security. Does it say something about IT policy? Assuming so, you need to ask your system administrator to change the IT policy setting for your handheld regarding installation of third party applications.
