Fresh or repair install corel 7

I am thinking of reinstalling Corel X7 because of some software bugs that I can't get rid of.   Latest build 7.4 hasnt helped.

I was wondering if its possible to do a 'repair install' that would leave all my macros intact or do I need to do a totally fresh install. 

I have a few macros installed that are going to be a total pain trying to figure out where and how...  all the install files are and how they were installed etc.

Also, is there somewhere where I can download the latest build or do I have to use the origlnal install files and then patch.

Thanks in advance
