Bug Missing My Old Rank and Weapons!

Hey! Recently, while scrolling through the servers I had in my list, I found MC-WAR. I remember how fun it used to be when my friend and I played it together and I decided to let my other friend try it out. When I logged on though, I realized I had lost my rank and all my weapons. The last time I played this game was maybe 1 or 2 years ago. I remember logging in maybe last year and still had all my stuff but I didn't play a match cause nobody was on. Now I see that the whole thing has been updated but I lost my rank and my weapons. Is there anyway to get them back? My username used to be Meep_926 or Meep_0926 if that helps at all. I changed it to The2kWehrmacht though last year. Also, the only gun I remember having is the MSR but when I checked, now it only requires level 7. I don't know if it has always been like that but I'm pretty sure it was a higher level to unlock it back in the old MC-WAR. Anyways, any help is appreciated. Thanks!
