I have been having a few issues lately with Windows 7 Pro with another CAD program regarding the saving issue. It is more when I sleep my laptop and upon waking the CAD program refuses to save the original file and brings up Save As which works. Once I have restarted the OS it is back to normal.
To rule out a problem with your OS can you copy/paste/save in other programs okay?
I have another old laptop using Windows XP and TC constantly crashed even when left idle when TC was running. Saving and sometimes opening drawing it would just bomb out for no reason. I ended up creating a new user account which worked. Microsoft likes to update our machines security measures with our file systems some of which are set to read only and some of them I cannot change for full access...
This may help also if it's part of Windows 10:
How to turn off User Account Control in Windows
You want to turn off User Account Control (UAC) in Windows so you can troubleshoot a software issue or to allow your program to run better, especially when it interacts with other software.
UAC is a Microsoft security tool that helps prevent intrusion of malicious software. It is not full-fledged anti-malware or an antivirus, but it does notify you of changes about to be made to your computer.
For troubleshooting application problems, temporarily disabling UAC may help pinpoint the problem or relieve the issue.
To turn off UAC:
Click the Start menu and in the search field type UAC.
Click "Change User Account Control settings."
In the window that comes up, move the slider down to "Never Notify."
Click OK and then restart the computer.
Note: UAC is not a part of Windows XP or other Windows systems prior to Windows Vista.
