Upload the attachment via MPGH... Go to your post, click edit. Go to advanced, and below where you submit your post there should be additional options. Look for manage attachments and upload your file. Remember to pack it in a .RAR...
Also, external downloads links are not allowed...
EDIT:
Need Virus Scans as well. Upload the file to Virus Total, VirScan, Jotti's Virus Scan, etc - and then post the link in your thread. You need at least two virus scans.
EDIT: Not even your source... This is Topblast's source. It's patched for good I believe. Can't be unpatched I believe.
No VS?
