So lately i was playing this mod all the time i have, and just started to looting sime fine equipments.
I have a lvl29 warrior with low on luck, because usually i loot horrible items, so the leveling up is kinda hard.
So the thing is, i usually playing with my roommate in LAN, without bigger problems.
BUT:
When we tried to trade once (not just throw on the ground and the other one picking up) the game froze, and after that we lost most of our equipments which was used by the characters (swords, bows etc (including some set items -.-") she is a lvl26 rouge.)
So since then, we always dropped the items on the ground and the other picked up, but it was very annoying after salvaging items and dropping a ton of gems etc.
We decided to trade, why not...
She inserted the gems and oils and stuff, i clicked on the accept button, but when she clicked on her's, the game is froze again.
After a while, she timed out, and the game exited for her to the main menu, and the freezing is stopped for me (i was walking in town etc.).
So it was quite lately, we decided to stop playing after this, and call it a day, so i exited the game too, and we gone sleep.
Today we wanted to play again, but when i try to host a game, it is crashing "the application stopped working blabla" windows window, loading for a few secs, and closes diablo.
The loading screen pops up tho, after selecting the character and the difficulty, but it is crashing immediately after it.
I tried to start every kind of game (single player, every diff..etc) but no luck, same crash all the time.
I have a lvl8 necromancer (actually i didn't like that class so i stopped playing it), and it is working fine on every mode, so it must be the save...
Can you please help me guys?
I'm having very rough days now, and don't feel i could start a new character, i would just delete the whole shit, but it would be bad, because i love playing it

Is there any fix to this?
Or is there any makers who can check my .tchsv file what the hell?
Thank you very much, and have a great day!

ps.: my game haven't crash when we tried to trade, it just froze until my flatmate's game timed out, after it, i could walk and stuff.. Exited normally....
