A current example: I had Taxman2012 that 2013er version have now been installed, the data transfer went smoothly. Now I have the whole weekend made the tax return, was now on EÜR create and wanted to look like some bookings last year look, which is why I started Taxman2012 again. After a fatal mistake, because as it turned out afterwards, has overwritten my Taxman2012 the control file of Taxman2013. Class, the work of an entire weekend gone. No idea who is doing the quality assurance at Lexware (probably exists, the department did not), in any case should not occur such a fundamental error.
If someone has already purchased the software and no longer able to return, I can only recommend the following two ways:
1. leave every 10 minutes through a backup of the backup Taxman
2. (as another Rezendent wrote: Put your own Virtual Machine and Taxman in a very insular area install)
For me it was the last time I will now make the tax return again by the tax consultant ... may cost more money, but I am annoyed not go around wasting an extremely long time.
