Thank you for giving the basic details of your computer but perhaps it would have been a better idea to insert them as part of your post, rather than as the thread title!
However, exactly which version and variant of MEP do you have? I suspect it may be an "older" version and the error is being caused because Google made a change to their Maps API, which your version of MEP cannot now use. In this situation I think you have little option but to look at updating your version of MEP, although the fact you are still running Win 7 will necessarily limit your choices since that OS is no longer supported by Microsoft and hence by Magix.
