Sprite Backup not working on xda iq

[Guest theodotcom]

Hi

I have sprite backup 5.2.0.1517 and need to backup my xda iq on o2 so i can keep my settings for my upgraded phone which is an xda graphite. Both phones run WM5 smartphone.

However when trying to backup the iq i keep getting the following error displayed on the handset

Error (1): Loadstring failed for 151

I've tried to run the file from the handset but it just starts loading and then the device freezes until i press the home key or switch it off.

Can anyone help?
