We are aware of the issue that you described, and we will do our best to fix it for CodeXL 2.0.
For now, please use MS Excel or any text editor to open the Statistics.cxltxt file (which is in plain csv format). It is not as comfortable as the GUI, but it will do the work until the GUI is fixed.
I have experienced the same problem as you with CodeXL 1.9.10: whenever I was trying to take a look at the statistics I had this message.
However, just switching the locale of my system from windows 10 FR to windows 10 EN did the trick. So it seems that it is just a problem about the locale.
A random guess is that it can not parse the statistics file correctly because it would expect commas instead of semicolons when I use my french locale, or something like that.
I guess that just by switching the locale of CodeXL to EN at the startup of the application would prevent a lot of bugs: it is not the first time I encounter a bug with CodeXL just because of the locale. It is super easy to do with Qt.
Thank you for this input, Ziple. We do our best to get it fixed for CodeXL 2.0.
