@acer hi! It is perfect. You recovered all of the important parts thank you so much! I will get my maple updated as soon as possible. Have a great day.

@acer hi again. This might do the trick, since I am at least able to see that the file contains 1 mb. I am having some trouble with unpacking it though.

Zip file:

test.zip

@acer I tried to convert the file to a zip file. Hope this works else write to me again. :)

Notes_to_Introduction_to_Probability_Theory.zip 

@acer 

Thank you so much! You saved all the important part! How did you do it?

Kind regards chri69a9
