Hi Arrowglass
Now that GTS is no longer supporting your Adagio installation (and I may add at the risk of offending someone reading this that they really never did a great job of supporting Adagio even when they said they did), your choices are:
1) Spend the time and energy to learn Adagio better - you have made a good start by finding this forum and the webinars recommended by Softrak Support are a great next step
2) Find a replacement Adagio consultant
3) A mixture of both
Adagio is not that hard to learn, and Adagio consultants are not that scary, so your options are not terrible.
