Elements 11.0 Constantly Crashing within a second or two of using

Hi there,

I have an older version of Elements - the 11.0 version. It is installed on my Macbook. I have macOS Mojave 10.14.2, MacBook Pro, Processor 2.7 GHz - not sure if this is all the info needed or not.

It was working fine up until a few days ago and now just shuts down within a couple of seconds of using it.

I have run every update I could find and tried a couple of the problem solves, including deleting and re-installing! Nothing is working. Please help! I really don't want to buy a newer version if at all possible.
