FPC glitch :( help?

[FLAOFEI]

When I load my own sounds in to FPC (Drumm machine software thing that comes with FL) When I load my own sounds to the pads it causes some sort of glitch in the program.
While a drummloop is playing in pianoroll or in the playlist I have to pause before I go to anywhere else in the playlist or pianoroll, or else it glitches and says "Access violation at address 02484810 in module 'FLEngine.dll'. Read of address F28B5627." Then FL becomes unresponsive, I have to close and reopen it (sometimes without getting the chance to save my work).

So. Anoying as hell plugin. Could anyone give tips on either alternative programs to use, or how to solve the problem.
Aprichiate an answer, since im gonna be getting myselfe some sort of pad controler sooner or later.

I think the Poise VST looks similar, but it costs $50...dunno about the demo's capability. I'm really bad at diagnosing bugs, I usually end up smashing my keyboard, sorry. :/
