I've registered/bought the software but I have some problems

I’ve just bought Xls Padlock. I have some problems. I wrote email but I got no reply.

1- “Protect the workbook with following password…” is not working. If I put a password, it is crashing.

2- I can not select “Build for Excel 64 bit”. It is gray…

3- It takes so long time to open the Exe file every time.
