Troubles with Expansion Memory

[CRTin4K]

I have a 10MB expansion board for my XVI that I ordered from BEEP many years ago. It was working fine until I bought a third-party MIDI/RAM expansion board. I never could get the third-party board to work properly, so I put my BEEP board back in. Now I can't get it to work. I used to be able to load games like Street Fighter II and Strider, but now they just give me an error and load back into Human 68k. My OS only shows 1355 KBytes available. I'm really worried right now that I've fried this system. Is there anything I could do to try to fix it?

I just wanted to add the details that I have a XM-6BE10, and a Etarikashikoshi X68000 – 8mb ram / MIDI board. The XM-6BE10 used to work. I can't get either of them to work now. I also have a System Sacom MIDI board and I can't get it to work either. I had never tried before due to lacking a bracket for it. I have tried a plethora of settings in switch.x and the memory is never recognized. It would appear that there's either something wrong with the system, or all three boards are dead now.

Does the card have a switch to change the memory address that you may have changed?
