Flash Player Issues

Hi,

I'm currently studying for ACA via distance learning and I have access to a portal which lets me study for mock exams; training etc. The problem is whenever I start a test, about half way through it just decides not to load anything, despite repeated attempts to refresh the page. I contacted tech support who asked if I had an up-to- date version of Flash, which I do, and it's enabled, but she seems to think that it's an issue with Flash not being up-to-date. I know it's installed because I came to the Adobe page which troubleshoots common issues, and it asks if you can see an animation of a tree with moving clouds, which I can, and this means that Flash is correctly installed. I have Windows 10, and when I go into manage add-ons in the browser settings, I can see that Flash is enabled. Apologies as I know it's not a directly related Adobe issue but I just wondered if there is anything else I could try or what it could be? Thanks.
