Filemaker 9 crashes when running SMTPit

[porterble]

HI,

We run a filemaker 9 database with SMTPit as the email plugin. The dabatase is shared on the network and we are getting the following error when sending an email from 2 of the computers:

The previous script step “Set Field” could not be completed because of an error. Do you wish to continue with this script?

I have upgraded the plugin from 4.1.10 to 4.1.13 but the problem still persists.

Is anyone able to assist with this? Do you require more information?

Thanks,

Nathan
