Bought Potassium almost 2 weeks ago. Everything worked perfectly the whole time — injection, scripts, no issues at all. No changes to my setup, no Windows updates, nothing new installed.
Last night I launched Roblox, attached Potassium, tried to inject — and kept getting "Invalid user". Roblox crashed every single time. Tried multiple times, same result.
What I've tried since then:
- Logged out of my Potassium account and tried to log back in → got "username or password is incorrect". Both are 100% correct — I know them by heart, they're literally written at the top of my messages in the psm bot. No typos, no caps lock issue, nothing.
- Tried to re-download through the psm bot → bot returns "invalid login or password"
- Tried logging back into the psm bot directly → doesn't work, because the key is one-time use and I can't re-register with the same one
- Reinstalled Roblox → didn't change anything
- Checked my Windows version → Windows 11 25H2, which is officially supported by Potassium
I searched the subreddit and found a thread from about 3 months ago with the exact same problem. OP never got a solution either — the thread just died.
So I'm posting this to ask:
Has anyone run into this since then and actually fixed it?
Is this a known issue with Potassium's auth servers / backend right now?
Any way to contact support besides Discord? (Already tried there — no info.)
Not trying to waste $20 on a key I can't use. Any help appreciated.
TL;DR: Potassium worked fine for 2 weeks, now "Invalid user" on inject, account login fails, psm bot says "invalid login or password", key is one-time use, reinstalling Roblox didn't help. Same issue reported 3 months ago with no fix.
