Try removing or renaming the entire wekafiles folder. This is the folder
that holds all the packages and configuration info for WEKA. It is normally
located in your user home folder.
Cheers,
Eibe

Mark,<br> <br>
Firstly, complements of the season and the best of wishes for 2019!<br>
<br>
I am not new to Weka: I have been using it for two years now without issues.<br>
Recently, I have been running Weka Version 3.9.3 on a Windows 7 32Bit Acer<br>
Aspire without any issues for two weeks. (I am using this machine in the<br>
interim; my main machine developed issues that are currently being<br>
resolved).<br>
<br>
Recently, I tried to install Weka's Python Package via the Package Manager.<br>
The installation failed and the machine crashed. I have since managed to<br>
restore it. And, I uninstalled the failed installation via the Package<br>
Manager in Safe Mode. <br>
<br>
Initially, Weka worked, but crashed just after I had converted a nominal<br>
attribute to a string, and; attempted to run the string-to-word-vector<br>
filter on the same attribute.<br>
<br>
The problem I face now is whenever I try to run Weka, even after<br>
uninstalling and reinstalling both Weka and Java, I get the following<br>
exception:<br>
<br>
<br>
Could not initialize the GenericPropertiesCreator. This exception was<br>
produced: java.lang.NumberFormatException: For input string: " \
".<br> <br>
<br>
Here is the output of the console:<br>
