Emergency laptop crash- how to recover data?

My laptop crashed, i think it might have started to get too hot as i was running a 3d computer design program called sketch-up (by google) anyhow its crashed just as ive finished my work and about to save this is 7hours solid of work that ive been doing with 36hrs till university deadline. with all the other work i have to do i cant afford to lose this plz tell me is there a way to recover the data. if over heating is the problem will this help, cos i cant afford to lsoe the data so i have left it on, placed it in a very cold room and hope a nice 4/5hrs of cooling down will allow it to work well, i will be looking on the web tho to check if this is nice or bad so i may change this if it turns out to be damaging further.
Answer
I would, walk softly, let it cool off and, try once more..omg, i can feel ur pain..it is possible that it is still there but...slimif you had the program downloaded to the laptop, it is possible that it might be recovered. if you were working off a web based program..i highly doubt it..once the website closes....nice luck~!
