Hi, Thanks for first responses. My reason for looking for 8.11 ... 8.14 is: A rumor says that 8.15 has problems with German XP and I am in Germany. Additionally I have problems with 8.10 (which I momentarily use) when using MELABS PicBasicpro within the IDE and perform a PROJECT SAVE AS. After that I'm no longer able to compile my sources, a message pops up saying "Invalid file format. No information available", my output window says BUILD SUCCEEDED but the hex file is corrupted, it contains fragments of assembler code. All very strange.... If anybody has similar problems and has another solution - thanks for help.
