Garrysmod.org uses steam accounts, they've got some fancy set-up with valve so you can log on using that account.

However yeah I do have to once again point out that what you're asking us to do here is not a huge favour, it's a MASSIVE favour.
It takes hours upon hours to create a good looking model and animate it, and then off to worst part which is getting it functional into the HPL engine.

.ent files are not models, they're simply files created with the HPL model editor which basicly contains information on the object and how it reacts in the game world.
The models use the OpenCOLLADA .DAE file format, which if you're a max user does not function properly and will certainly cause alot of problems.

Then you're going to have to get yourself an image editing program and support plugins for Nvidias .DDS format. Upon exporting your model to the Amnesia directory you're going to need to have the .dds texture already located within the same directory you intend to export to such as /entities/enemies.
This DDS texture must be applied to the model in your editor of choise otherwise the pathing will be borked and your model will be invisible in-game.

Once you've exported the model you should load up the modeleditor.exe which comes with the leveleditor. From there you should probably just load p for example the grunt .ent file, replace the model with yours and then save it out under a different name so that you're not overriding your original grunt.
