1. Installing Cross+A
I used the previous version of Cross+A (added new words and edited existing descriptions in the program's database). Now I have download a new version of Cross+A. What must I do to keep my changes in the database?
Before the the new version installing it is recommended to copy the file crossa.dic from the folder 'Documents\Cross+A' to the temporary folder. Install the new version of Cross+A, run it and choose the main menu item File|Text File Import. Choose the name of the file crossa.dic saved in the temporary folder and insert words into the new database.
Should I uninstall an older version of Cross+A before installing the newer one?
Yes, we strongly recommend you to do that.
The program fails after startup. What is wrong?
It is possible that the program conflicts with DEP (Data Execution Prevention). Try to disable DEP for Cross+A: Start -> Control Panel -> System -> Advanced tab -> Performance -> Settings -> Data Execute; select Turn on DEP for all programs and services except for those I select and add crossa.exe to the list of programs.

No, the program supports the automatic mode of the puzzle solving only.
I tried to solve the nonogram puzzle 50 x 50 in Cross+A, but even after few hours the puzzle was not solved. Why?

Yes, the created puzzle has only one solution.
