Icons and start menu doesnt apear on my screen. Help!

Ok so, I closed maple, and tried to start it back from the website. Didn't work. Tried starting it with game launcher. Didn't work. I rebooted my pc, and when logging on my user session, the icons and start menu weren't there anymore! the only thing i can do now is open the task manager and click: File->New Task and enter the web adress to go on the internet. I can't even open a program, nor start maple from the website. Also, i had frostwire open when i first rebooted my comp, so i don,t know if it has something to do with it. Please help : /

PS: I use windows xp 16 bits if it may helps.
