Server mb limit?

Hello to all , I have a very strange problem:

I have downloaded much skin and gun but when I try to play my listen server my friends (that have my same client) can not connect..

So i have read of the gun limiti, I reduced the number of the weapon and trying several times I found the limit of the max weapon, but I've seen that in this limit also belong the skin, because removing them all, it works but not putting them, so there is not only a maximum number of weapons, but a real number mb maximum for the server? :confused:



And I do not understand why only biotics lab works the others maps not , perhaps because the other maps weigh more? Thanks in advance
