Xlspadlock improvements

Hello,
I purchased your xlspadlock program and I love it. I have tested version 2.4 with 64bit and one thing I noted is that it takes a while to save the workbook and sometimes the computer hangs when it tries to save the workbook.
I have also tested the php keygen sdk and its not working as desired because it is telling me the keys that it generates is not working with my program.
Also the online activation kit is a pain to make it work because the documentation is not clear enough. I get various errors when I tested it.
If I can get the php keygen sdk to work then that will be good enough.
There needs to be an improvement on the user guide concerning the online activation using php sdk and using the activation kit.

The problem is that you must have good PHP skills to work with our PHP SDK. Documentation will not cover everything because the SDK is general and there are so many implementation possibilities!
We noted that the 64-bit version was slower for some tasks. We hope v2.5 will solve that.
If the key generator is not producing working keys, it’s certainly your application master key that is not properly defined.
