My protools is uninstalled and won't reinstall

[StrugglingGary]

There is more to it than that and sorry I am very new to all this. Last night I finally found where to download my virtual instruments and plugins that come with protools and after installing them protools wouldn't open, didn't give any messages about why it wasn't opening it just wouldn't. so I turn my computer off hoping it'll sort itself out in the morning. it's the morning now and it is still not working and so I try to remove the plugins folder to get it started but they just won't load and I try most the other solutions on the forum for protools not starting but now I have uninstalled protools because of some forum that was recommending that for an update but now it won't reinstall and I am very lost, and any time I try to reinstall from the avid website it doesn't work and says contact customer support. Any advice is very much appreciated.
