Using the Steam version of WaW and I bought a new laptop recently. On my old laptop, the installer worked no problem, but with my current one, when using the installer I get the following pop up notification:

_________________________________________________________________________________________________
Zip Extraction Error:
ExtractToFolder(
"C:\Users\*username*\AppData\Local\Temp\UGX Map Magager\Cabin%20v1.1.zip",
"C:\Users\*username*\AppData\Local\Temp\UGX Map Manager\Cabin%20v1.1\",
True
);

Exception Message:

Unexpected EOF

Installing the downloaded map failed. The downloaded zip will be kept in the user temp folder until the program closes.

Help"
Because the specific point at which the install failed is unknown, nothing will be erased from what was completed of the install. However, the zip file downloaded is kept in your user temp folder. You may use it to see what files should be installed, and delete ones that successfully installed if you'd like..

Error Code - Please show this to [UGX]Aidan:

I really have no idea why I keep getting this error and I've searched the FAQ and the depths of the forum extensively and have found no solution. Any help would be great.
