Gæti verið að hann sé að reyna að senda í gegnum msn og msn sé að blokka á það. “Poteantially dangered file” eða eitthvað helvíti!
Annars til að losna við þetta, fara á www.mess.be, flettir svo neðst og ferð í ">> News Archives“. Ofarlega er svo ”The week of April 03 (2005)".
Svo skaltu leita af þessu:
Back to free trade: Say NO to blocked file extensions!
dwergs says:


Want to send your mates a picture of your new girlfriend, a demo of your amazing guitar talent or that funny videofile you downloaded from Ebaumsworld? But is MSN Messenger randomly returning them a message that "[user] tried to send you a file (filename.mp3). This file has been blocked because it is potentially unsafe."? Potentially!? Microsoft is operating way beyond their authority with the blocked file extensions strategy (well, maybe they permit themselves in the ToS somewhere) and I'm sure they're chasing potential MSN Messenger users away.

But as usual, you can rely on us in times of need. Together with wtbw, we made it easy for you to enable the transfer of blocked file types again. Launch the simple File Extension Unblocker and restart MSN Messenger completely. You'll notice a lot less obstruction when transferring files afterwards!

Þarna geturðu sótt þetta, til að losna við þetta.
Það virðist ekki vera hægt að benda beint á þennan link, maður endar alltaf á www.mess.be bara.. sakar samt ekki að prófa.



Ef hinsvegar þetta er ekki málið, þá bara síðan sem Spyro benti á. ;)
