When you say you have now got it upgraded to 1.39h, when did this happen? as 1.39h was released about 5 yrs ago,
1) Have your issues happened recently,
2) is this template something that was installed by the original developer, or have you installed it recently
3) Normally with these templates there is some sort of instruction manual pdf file, that explains how to set up the slides, were you given these when the site was set up?
