Yes, Macola ES is a new product, and yes, there are some problems with the product that have yet to be worked out. It is in fact a controlled release product, and yes, I would not attempt to put myself through an install at this time.
However, with that being said, I believe that with the proper support of a Macola reseller and active participation by the end user the product can be implemented successfully. If the Macola reseller is willing to put the time in to the matter I'm sure that your implementation will be successful. What's more is that being part of the initial install base provides you, as an end user, with a unique oportunity to have some of the special features, that are unique to your business type, implemented in the product.
I would warn you that it will be a bit of a rocky road, but certainly the road is not washed out in front of you. It is important that, as a end user of the product, that you work with individuals who are focused on solutions rather than on the problems. If you feel that you are not being served "solutions" at this time, I would suggest contacting another reseller as Don has suggested you do earlier in this thread. I would not suggest pulling the contract, because in this situation there is no way to win.
For What it's Worth,
