help opening Captivate

Can anybody help me ? I have just downloaded captivate free trial and when i launch the app , it says Adobe Captivate has stopped working. I have just been made redundant and trying to brush up on my skills by downloading AC on my laptop…. it is not going very well so far ! system capability from what i have read seems ok 2.60GHz 8.00 GB 64 bit OS Windows 8.1
