MoP Client not launching; process starts, does not use any RAM

So, recently decided I'd get back in to the Frostwolf server so I re-downloaded the MoP client (the extended one). When it finished downloading, I launched the wow.exe file in the folder provided. Strangely enough, nothing happened. I waited a few minutes and still nothing. I ended up opening task manager to see if the process was running. Surely enough, it was running, however, it was only using <5000k bytes of ram, as opposed to >200k bytes when the client is actually working. Also, it was using 0% of my CPU. Furthermore, it gives a message a few minutes after launching stating that it can't make a required change to an archive file because it didn't have a write permission. I checked to see it's permissions, changed it so it DID have write permissions and even launched the program as an administrator and still nothing. I'm currently running a file validity scan to see if there are any missing/corrupted files, but I'm doubtful there are; as soon as it finished downloading it didn't work. Does anyone know of a fix for this if they've has this before?

Check these settings and maybe manually set it:


1. Open System Properties. Right-click the Start menu, select System and then click Change Settings, or use the Control Panel.

2. In the System Properties dialog box, on the Advanced tab, click the Settings button in the Performance section.

3. In the Performance Options dialog box, on the Advanced tab, click the Change button in the Virtual Memory section.

4. In the Virtual Memory dialog box, jot down the minimum allowed, recommended and currently allocated paging file sizes in the last section. Then, uncheck the box that says Automatically manage paging file size for all drives. If more than one drive appears in the available drives list, click your system drive -- the one on which Windows is installed, which is usually C:.

5. Click Custom Size, and then type values into the Initial Size (MB) and Maximum Size (MB) boxes, making the maximum size 1 GB (1,000 MB) or up to 4 GB (4,000 MB), depending on the amount of installed RAM.

6. Click Set, then OK.

After these steps, close all open dialog boxes and restart your computer.
