CHIRP

My radio is a Retevis H777 model. I tried to transfer a new image file and i get four errors.
The first issue is that on COM3 when i try to send it over it clones however the bar doesn't move at all i left it for an hour with no change. I cancelled the process seeing it wasn't going anywhere and tried again the the error was could not open port COM3: [Error 5] Access is denied. I then tried the other port listed i.e. COM9 which said Radio refused to enter programming mode (this was previously what happened on COM8 however when i uninstalled CHIRP and reinstalled it it switched to COM9 for some reason.)
I tried going through the various ports however all except COM4 said could not open port COM2: [Error 2] The system cannot find the file specified. Obviously not all of them said COM2 it was the number of the port respectively.
COM4 said could not open port COM4: [Error 121] The semaphore timeout period has expired.
They were the only four errors i got however if i restarted it would let me bring up the same non moving clone bar on COM3 before me cancelling it and the process repeating.
I've tried restarting, uninstalling everything and nothing has worked.
