Yes I have the full version and have for quite some time. The support guy at DataViz says that they are aware of the problem. I use this software to invoice my customers and not having the ability to edit the invoice and save it is a problem to me. This is a potential loss of income for me as it is very difficult to reconstruct the activities of the day when I get to my desktop at home. I need this software as it is critical in my business. Data Viz has acknowledged the problem and I would think the 15 days should be enough to at least come up with a solution or a work around at least.
If the software is mission critical, then you need to immediately develop a fall back plan. For example, do you have a desktop, laptop, netbook, or tablet available to capture the information? All kidding aside, can you make hand written notations, logs, etc. and then transcribe them at a later time when it is more convenient? The technology should be working for you and not the other way around. That being said, it sounds like a little bit of contingency planning is in order here.
I do not know what the economic impact is for you of the potential loss of data, however if the downside is significant, then perhaps you should also consider using a different device, even on a temporary basis. For example, Docs to Go works on the iPhone and Blackberry platforms, as well as Android. You could also pick up a different Android device that is still capable of working with DTG.
Was your business started or created prior to the intro of DTG? If so, how were things done in the "old days"? What about a cloud based solution?
I believe that if you brainstorm this long enough, you will come up with a viable solution. Dataviz may not be able to resolve your problem as quickly as you would like. Therefore it is not advisable to be so dependent on a sole source vendor in this case. I recognize that my commentary is very much "after the fact", however you will get past this and want to plan for the next time, which there will always be.
I used to work in a state of the art technology environment for Citibank in the early '80's, and that's when I learned about the importance of risk assessment and contingency planning.
It also sounds as if you are using some form of a template. Maybe a backed up copy of an earlier version can be tweaked in a way that will work, even on the new version.
I hope that you find a solution asap. Good luck.
