installation package could not be opened
 

i downloaded the beta 2.3.1 I think because I read elsewhere that it would not have the problems I was having with the previous one. It downloaded, said it had transferred 3.7 MB, but then that instantly changed to 1.7 MB transferred, and the message "Size mismatch". It won't open because I get the message "installation package could not be opened", and that I should contact the vendor to check that it is a valid windows installation package or something. I know I downloaded the windows one and everything, so ?.
