Dont buy this - everything keeps crashing

I tried the lite-Version, that is crashing every time. This Bug-Makers and Crap-Sellers wrote that it is only in the lite-Version, so I bought the full-Version.
Full-Version means full of Bugs and your money gone away. Both versions keep crashing, so never trust the lies of this company. I was not able to enter a single book. 3,99 EUR for nothing but crashing ....
STAY AWAY FROM THAT COMPANY!!!
