I tried downloading it from momchil's forum page and copy-pasting it
What did you copy and paste?
There are 2 links at the top of the page.
You can right click
> Save target as
or you can just double click the link to download the latest file.
Please be aware of the extension: poclbm_py2exe_20120205.7z
The 7zip archive/extract tool is not installed in Windows as it is third party software.
If you don't already have it you can download from here: http://7-zip.org/
When extracting, right click
the poclbm file > extract to new folder. Allow it to use the file name to name the folder.
You will probably have to replace the old files with the new files from the extracted folder C:\Program Files (x86)\Bitcoin\poclbm_py2exe_20120205
There are 24 files total.
The only other issue possibly is poclbm.ini which is located in /appdata/roaming/, ...I don't know if you need to mess with this or not.
Q: How can I delete my miner settings, or edit them manually?
A: Miner settings are stored in %APPDATA%\Roaming\poclbm. For example, on Windows 7 this path translates to C:\Users\Kiv\AppData\Roaming\poclbm. The file poclbm.ini inside contains the settings in JSON format. There are also some settings in .ini files inside the miner directory, also in JSON format. No registry keys are used, so removing these .ini files completely erases your settings.
In the GUIMiner thread there does seem to be some issues with the latest poclbm.https://bitcointalk.org/index.php?topic=3878.1120https://bitcointalk.org/index.php?topic=3878.1140
