Can no longer access my Dashboard or even view the site! Help Pl

I cannot access ANY PART of the site no longer, what i was doing, is i was using the cubepoints plugin, and i went to edit, (i wanted to see if i could Hide/remove the “Donate” button) and found the lines which i thought were the code, hit select all, copy it, (so if it went wrong i could paste back in the original text) when i removed the lines which i thought was the donate button, the page went white with this messege:

Parse error: syntax error, unexpected $end in /home/[my username]/public_html/wp-content/plugins/cubepoints/cp_widgets.php on line 97

And i get that messege, when trying to access ANY part of my dashboard, as well as going directly to my site.

(I did not use a FTP client to install wordpress, i used fantastico via HostGator. I been hard at work the past 3 days on my site, and even had lack of sleep last night [uptill4] i really dont want to have to start again, Please Help, thank you.)
