WPMU Prosite Plugin making my site slow


I hope you are having a good day.

After activating the WPMU Prosite Plugin my site becomes really slow. I also asked on the forum on how I can fix this problem. I got a response and tried to fix it but it did not help at all.

May I send you the Admin username and password of my site to you so you can fix it from your side?
Please do let me know to which email id I can send this information to.
