Downloads showing up as text file?

More then a month ago i had downloaded version 2.6 (i think it was) and everything was working out great!
But, when i updated to version 2.7 it started messing things up. Whenever i clicked the download button, instead of a save as/open prompt i get the file showing up as text in my browser like this:

And so on and so on…

Ive been trying to figure things out myself; checking file permissions, re-installing (numerous times), clearing the database, manual uploading files into the correct folder.. Nothing seemed to work…

I’ve let is rest for a couple of weeks and decided to give a go at it today again.. Same issue..
Completely cleared everything that has to do with wpdm including database files.. Did a complete fresh install but again, and after fixing the upload permission thing (neverending issue: chmod 777 is the only thing that seems to work), again the download files are showing up as text..

I think it has to do with the file permissions meaning that it’s readable, but not excecutable..

Either way, i cant figure how to get it working again, so any help is much appreciated.

a link to the page were a test file is set up atm:

Oke thanks, much appreciated!

Thauhid,

For some reason, im having problems again.. Dunno why. After you’ve fixed it, the only thing ive done is re-upload the two files i had prior.

This is what im getting now:

Getting this on 50% of all page loads:
