My Plugins crashed after uploading jevents pro packages and I do not know how to fix it,

When I click the plugins under extnsion manager i get an error see below and I cannot access any plugins on the site
Error
Reinstalling Jevents I get an php out of date warning but my host will not update past 5.538

Some help would be appreciated please
