I had a hard drive crash and had to reinstall a backup of the software that I made. To avoid this in the future, you should make a backup of the database which the software does allow for you to do. I reinstalled a different version of the software on the machine and restored the database without an issue.
Instead of posting this to the web site that is slandering the company, it would be better for you to post this online to a different web site and ask for assistance. There are many computer users out there like myself which could have helped you in this situation. If there is anything that I learned from my hard drive crash is the true benefit of having routine backups. If it weren't for this, we wouldn't have been able to recover the data. This is not necessarily the fault of Neat Co as the software allows for you to export, import, and backup their proprietary database.
You also can sell the scanners on eBay to recover some of your funds. The software is very well done, but I agree that it does not have a power-user option to allow for you to manipulate or correct data using SQL Server Compact edition that would allow for you to correct the database or have someone correct it for you.
