BPF 'Method '~' of object '~' failed' error

Hi Experts.

we are experiencing quite a lot of  'Method '_{' of object '}' failed' when trying to open a template from a BPF. The templates work without problems when we open them from etools\Open dynamic templates but randomly they fail when using the BPF. We have cleared the Client Options and it stills does not work from some PCs (other users enter into the templates without problems).

Any idea?

Thanks a lot for your support!
