My trados copy is not doing what its supposed to

Hello all. I hope someone can help me out on this. This problem arised while I was taking a TRADOS course on a platform called Traduversia.

I want to créate a translation Project. For that, I have the folder in which I have the files my PC Downloads. The files are 2 TM´s, 1 autosuggest dictionary and a term base plus 3 word files, a PDF and a powerpoint document. I get to the trados welcome page and tried to upload the Word, pp and PDF files and for that I have to get into the principal folder, which has all the documents.

When I try to get in that folder, it doesnt let me. Puts the whole folder on the welcoming page.

I must add that the program adds the file as a ZIP file, but the file has already been decompressed

Since i wanted to have the individual documents to import them into TRADOS, I put them aside in the desktop and when I open the Project creator assistant, it doesnt let me import one of the documents saying that its being used in another application/program even though its not ooen anywhere else.

Also, later on this tutorial Im refering to, I wanted to fusion the Word files and it doesnt let me because it says one of the files (which is not the same as the other one it didnt recognize) cannot be found, hence, it didnt fusion the files.

Another similar problem arose when taking another tutorial .We´ve got pretty much the same type of resources as in the other Project in the other tutorial I mentioned earlier. Im in the Project window of the program and I go and click on new Project and after naming it I tried to drag the files into the Project and its just not possible. I can see you can do that because Im watching the tutorial. I have a new laptop and I just downloaded the program about 2 weeks ago or even less, so Im thinking there might be a problem of settings either computer settings or program settings.

I hope someone can give me an answer. Thanks in advance and have a Good day
