Plutonium

Hoping you we're having a good night i want to explain my problems with the black ops 1 launching in plutonium, i dont have problems to launch the game, but it doesn't record my progress, it is stucked in the level 49, i can get level up but when i get out and later i want to launch the game again, it still having the level 49 and all my progress is thrown away. checking what can make this error, i noticed that in the code bar when the game launches i can see an orange text that says "plutonium r3519" and i think taht can be the problem, i hope you can please help me with the inconvenient, i will be patient. have a good night
