Quite tricky and involved a lot of guesswork.

Too much guessing needed! Any hints?

It's certainly a miracle that I've solved this puzzle :)

For people who want to give it a try:
The five rows on the left are crosses and hearts alternated.

Awful puzzle, waste of time and the message is completely meaningless.

Thanks. Hint: R25/C5-C6.

Total guessing.
