Photoshop Elements 11 installation

I purchased Photoshop Elements 11 on 2/24/14.  After installing it and trying to create posters for a soccer team, the program kept crashing.  After numerous calls to Adobe with absolutely no luck at resolving this issue, I gave up and switched to Paint Shop Pro because I had to get 25 posters completed in less than 3 weeks time.  Now, I want try some different types of graphics and would like to use what I purchaed.  I am going to install this on another computer to see if that resolves the issue.  When I go to the the help section of the Adobe website it takes you to a page that says you can download old versions here.  What a joke!  Then it leads you to a step by step page but that says to "insert the DISC".  I never received a disc.  I am totally frustrated that I have paid over $100 for a product that I have never been able to use and now apparently cannot download from the Adobe site.  I guess the reason I have waited so long to try Adobe again is because my blood pressure  goes up every time I try to deal with this issue.  Basically in my opinion borderline fraudulent since their on employees could not solve my issues previously.  As you can see I am totally frustrated with this situation.  Is there anyone who can tell me how to reistall this product without the disc that I do not have?  Thanks
