Problem with audacity

I just recently downloaded the updated audacity and I am having major problems with it. The size of the recording is very small, I had someone help me and he couldn’t figure it out and he was an expert on audacity. I can’t edit the software because the size is way too small. I also tried to uninstall and reinstall and the size of the recording was huge and I didn’t do anything the software. I really need this fixed because I can’t record with the way that it is now. Any help would be greatly appreciated.
